+# 应用开发框架 - 项目开发说明
+
+
+[TOC]
+
+
+## 项目介绍
+
+
+### 公共类库
+
+common，提供公用的工具类、框架代码
+
+
+
+### 业务类库
+
+以 业务领域 为单位，实现 业务领域、业务接口，如：
+
+* system，系统功能
+
+* biz，业务示例
+
+每个 业务领域项目下，又分为 领域层 domain、接口层 api
+
+业务类库中，尽量以通用服务的方式实现业务
+
+
+
+### 微服务项目 sa
+
+将 业务类库 包装为 微服务，对外提供 RESTful API，以及相关的接口文档的访问、测试
+
+
+
+### 后端项目 bff
+
+提供 面向UI 的后端接口
+
+对服务接口的转发（建议，避免使用）
+
+对服务接口的聚合、裁剪、适配
+
+提供用户认证，保护接口的访问权限
+
+
+
+## 项目开发
+
+
+### 业务类库
+
+面对业务需求，设计时，进行领域划分，保证划分的粒度适中
+
+* 在 领域层 domain，创建 实体 entity、数据传输对象 dto、持久化 repo、业务逻辑 service
+
+* 在 接口层 api，创建 值对象 vo、接口 api
+
+#### 实体 entity
+
+```java
+package com.supwisdom.institute.backend.biz.domain.entity;
+
+import java.util.Date;
+
+import javax.persistence.Column;
+import javax.persistence.Entity;
+import javax.persistence.Table;
+
+import lombok.Getter;
+import lombok.Setter;
+
+import com.supwisdom.institute.backend.common.framework.entity.ABaseEntity;
+
+@Entity
+@Table(name = "TB_BIZ")
+public class Biz extends ABaseEntity {
+
+  /**
+   * 
+   */
+  private static final long serialVersionUID = 5503233707196628811L;
+  
+  @Getter
+  @Setter
+  @Column(name = "NAME")
+  private String name;
+  
+  @Getter
+  @Setter
+  @Column(name = "BOOL")
+  private Boolean bool;
+  
+  @Getter
+  @Setter
+  @Column(name = "DATE")
+  private Date date;
+
+  @Getter
+  @Setter
+  @Column(name = "NUM")
+  private Integer num;
+
+}
+
+```
+
+继承 `ABaseEntity`
+
+注解 `@Entity`，指定该 class 为一个实体
+
+注解 `@Table`，指定该实体对应的数据库表的表名
+
+注解 `@Column`，指定该属性对应的数据库表的字段名
+
+表名、字段名 都采用大写，多个单词用 `下划线(_)` 隔开
+
+
+
+#### 数据传输对象 dto
+
+```java
+
+```
+
+
+#### 持久化 repo
+
+```java
+package com.supwisdom.institute.backend.biz.domain.repo;
+
+import java.util.Map;
+
+import org.springframework.data.domain.Page;
+import org.springframework.stereotype.Repository;
+
+import com.supwisdom.institute.backend.biz.domain.entity.Biz;
+import com.supwisdom.institute.backend.common.framework.repo.BaseJpaRepository;
+
+@Repository
+public interface BizRepository extends BaseJpaRepository<Biz> {
+  
+  @Override
+  public default Page<Biz> selectPageList(boolean loadAll, int pageIndex, int pageSize, Map<String, Object> mapBean, Map<String, String> orderBy) {
+    
+    
+    return null;
+  }
+
+}
+
+```
+
+继承 `BaseJpaRepository<E>`，基类中，已经实现了基本的 CURD 逻辑，方法如下：
+
+* 分页查询
+```java
+  public default Page<E> selectPageList(boolean loadAll, int pageIndex, int pageSize, Map<String, Object> mapBean, Map<String, String> orderBy)
+```
+
+* 根据ID获取
+```java
+  public default E selectById(String id)
+```
+
+* 新增
+```java
+  public default E insert(E entity)
+```
+
+* 更新
+```java
+  public default E update(E entity)
+```
+
+* 删除
+```java
+  public default void delete(String id)
+```
+
+
+注解 `@Repository`，指定该 class 为一个数据持久化类
+
+其中 `BaseJpaRepository` 的 `selectPageList` 方法，默认返回所有数据，不会处理查询条件、排序，故一般都需要由业务自行重写
+
+```java
+  default Specification<Biz> convertSpecification(Map<String, Object> mapBean) {
+
+    Specification<Biz> spec = new Specification<Biz>() {
+
+      /**
+       * 
+       */
+      private static final long serialVersionUID = -1820403213133310124L;
+
+      @Override
+      public Predicate toPredicate(Root<Biz> root, CriteriaQuery<?> query, CriteriaBuilder criteriaBuilder) {
+        List<Predicate> predicates = new ArrayList<>();
+        
+        if (mapBean != null) {
+          if (!StringUtils.isEmpty(MapBeanUtils.getString(mapBean, "name"))) {
+            predicates.add(criteriaBuilder.like(root.get("name"), MapBeanUtils.getString(mapBean, "name")));
+          }
+
+          if (!StringUtils.isEmpty(MapBeanUtils.getBoolean(mapBean, "bool"))) {
+            predicates.add(criteriaBuilder.equal(root.get("bool"), MapBeanUtils.getBoolean(mapBean, "bool")));
+          }
+          
+          if (!StringUtils.isEmpty(MapBeanUtils.getString(mapBean, "dateBegin"))) {
+            String grantTimeBegin = MapBeanUtils.getString(mapBean, "dateBegin");
+            Date d = DateUtil.parseDate(grantTimeBegin+" 00:00:00", "yyyy-MM-dd HH:mm:ss");
+            
+            if (d != null) {
+              predicates.add(criteriaBuilder.greaterThanOrEqualTo(root.get("date"), d));
+            }
+          }
+
+          if (!StringUtils.isEmpty(MapBeanUtils.getString(mapBean, "dateEnd"))) {
+            String grantTimeEnd = MapBeanUtils.getString(mapBean, "dateEnd");
+            Date d = DateUtil.parseDate(grantTimeEnd+" 23:59:59", "yyyy-MM-dd HH:mm:ss");
+            
+            if (d != null) {
+              predicates.add(criteriaBuilder.lessThanOrEqualTo(root.get("date"), d));
+            }
+          }
+        }
+        
+        return criteriaBuilder.and(predicates.toArray(new Predicate[predicates.size()]));
+      }
+      
+    };
+    
+    return spec;
+  }
+  
+  @Override
+  public default Page<Biz> selectPageList(boolean loadAll, int pageIndex, int pageSize, Map<String, Object> mapBean, Map<String, String> orderBy) {
+    
+    Specification<Biz> spec = this.convertSpecification(mapBean);
+
+    if (loadAll) {
+      pageIndex = 0;
+      pageSize = Integer.MAX_VALUE;
+    }
+    
+    Sort sort = new Sort(Sort.Direction.DESC, "date");  // Sort.unsorted
+
+    if (orderBy != null) {
+      List<Order> orders = new ArrayList<>();
+      
+      orderBy.forEach((k, v) -> {
+        if ("asc".equalsIgnoreCase(v)) {
+          Order order = Order.asc(k);
+          orders.add(order);
+        } else if ("desc".equalsIgnoreCase(v)) {
+          Order order = Order.desc(k);
+          orders.add(order);
+        } else {
+          Order order = Order.by(k);
+          orders.add(order);
+        }
+      });
+      
+      sort = Sort.by(orders);
+    }
+
+    PageRequest pageRequest = PageRequest.of(pageIndex, pageSize, sort);
+    
+    return this.findAll(spec, pageRequest);
+  }
+
+```
+
+
+
+#### 业务逻辑 service
+
+```java
+package com.supwisdom.institute.backend.biz.domain.service;
+
+import org.springframework.beans.factory.annotation.Autowired;
+import org.springframework.stereotype.Service;
+
+import com.supwisdom.institute.backend.biz.domain.entity.Biz;
+import com.supwisdom.institute.backend.biz.domain.repo.BizRepository;
+import com.supwisdom.institute.backend.common.framework.service.ABaseService;
+
+@Service
+public class BizService extends ABaseService<Biz, BizRepository> {
+  
+  @Autowired
+  private BizRepository bizRepository;
+
+  @Override
+  public BizRepository getRepo() {
+    return bizRepository;
+  }
+
+}
+
+```
+
+继承 `ABaseService<E, REPO>`
+
+注解 `@Service`，指定该 class 为一个业务逻辑类
+
+注入 业务对应的 Repository，并实现 `public REPO getRepo()`
+
+
+#### 值对象 vo
+
+这里的vo，目前主要用于接口的请求、响应对象的封装
+
+
+
+#### 接口 api
+
+```java
+package com.supwisdom.institute.backend.biz.api.v1.admin;
+
+import io.swagger.annotations.Api;
+
+import org.springframework.web.bind.annotation.RequestMapping;
+import org.springframework.web.bind.annotation.RestController;
+
+@Api(value = "BizAdminBiz", tags = { "BizAdminBiz" }, description = "Biz示例接口")
+@RestController
+@RequestMapping("/v1/admin/biz")
+public class AdminBizController {
+
+}
+
+```
+
+
+
+### 微服务项目
+
+* 关于 Application
+
+```java
+package com.supwisdom.institute.backend.admin.sa;
+
+import org.springframework.boot.SpringApplication;
+import org.springframework.boot.autoconfigure.SpringBootApplication;

+public class Application {
+
+  public static void main(String[] args) {
+    SpringApplication.run(Application.class, args);
+  }
+  
+  @Bean
+  public CorsFilter corsFilter() {
+    final CorsConfiguration config = new CorsConfiguration();

+
+    final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
+    source.registerCorsConfiguration("/v2/api-docs", config);
+
+    return new CorsFilter(source);
+  }
+
+}
+
+```
+
+注解 `@SpringBootApplication`，
+
+注解 `@EnableSimpleUserTransmit`，从请求中接收 User 信息，通过 Feign 调用外部服务时，传递 User 信息
+
+注解 `@EnableCustomExceptionHandler`，将异常转换为符合开发规范的 json 数据
+
+注解 `@EntityScan`，扫描实体
+
+注解 `@EnableJpaRepositories`，扫描持久类
+
+注解 `@ComponentScan`，扫描组件，如 @Service、@Controller、@RestController 等
+
+Filter `corsFilter`，允许跨域请求，此处允许对路径 `/v2/api-docs` 的跨域请求
+
+
+* 在 pom 中，添加依赖配置

+      <artifactId>sw-backend-biz-api</artifactId>
+    </dependency>
+
+```
+
+* （可选）在 application.yml 中，添加业务相关的配置项
+
+
+
+### 后端项目
+
+* 关于 Application
+
+```java
+package com.supwisdom.institute.backend.admin.bff;
+
+import org.springframework.boot.SpringApplication;
+import org.springframework.boot.autoconfigure.SpringBootApplication;
+import org.springframework.cloud.openfeign.EnableFeignClients;
+import org.springframework.context.annotation.Bean;
+import org.springframework.web.cors.CorsConfiguration;
+import org.springframework.web.cors.UrlBasedCorsConfigurationSource;
+import org.springframework.web.filter.CorsFilter;
+
+import com.supwisdom.infras.security.configure.basic.EnableInfrasBasicApi;
+import com.supwisdom.infras.security.configure.cas.EnableInfrasCasSecurity;
+import com.supwisdom.infras.security.configure.jwt.EnableInfrasJWTApi;
+import com.supwisdom.institute.backend.common.core.transmit.annotation.EnableSimpleUserTransmit;
+import com.supwisdom.institute.backend.common.framework.exception.EnableCustomExceptionHandler;
+
+@SpringBootApplication
+@EnableFeignClients
+
+@EnableSimpleUserTransmit
+@EnableCustomExceptionHandler
+
+@EnableInfrasCasSecurity
+
+@EnableInfrasBasicApi
+@EnableInfrasJWTApi
+public class Application {
+
+  public static void main(String[] args) {
+    SpringApplication.run(Application.class, args);
+  }
+  
+  @Bean
+  public CorsFilter corsFilter() {
+    final CorsConfiguration config = new CorsConfiguration();
+    //config.setAllowCredentials(true);
+    config.addAllowedOrigin("*");
+    config.addAllowedHeader("*");
+    config.addAllowedMethod("*");
+
+    final UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
+    source.registerCorsConfiguration("/v2/api-docs", config);
+    source.registerCorsConfiguration("/api/**", config);  // 对 /api/** 下的请求，支持 cors 跨域请求，如不需要可以注释
+
+    return new CorsFilter(source);
+  }
+
+}
+
+```
+
+注解 `@SpringBootApplication`，
+
+注解 `@EnableFeignClients`，支持 FeignClient
+
+注解 `@EnableSimpleUserTransmit`，从请求中接收 User 信息，通过 Feign 调用外部服务时，传递 User 信息
+
+注解 `@EnableCustomExceptionHandler`，将异常转换为符合开发规范的 json 数据
+
+注解 `@EnableInfrasCasSecurity`，支持 cas，在 application.yml 可配置是否启用
+
+注解 `@EnableInfrasBasicApi`，支持 basic 认证（一般在开发环境启用），在 application.yml 可配置是否启用
+
+注解 `@EnableInfrasJWTApi`，支持 jwt 认证（一般在生产环境启用），在 application.yml 可配置是否启用
+
+
+
+* 关于接口请求
+
+后端项目中，使用服务接口的方式有 2 种，一是 请求转发，二是 远程调用
+
+
+#### 请求转发
+
+请求转发的方式，基于 spring-cloud-gateway 实现
+
+* 在 pom.xml 中，添加依赖配置
+
+```xml
+    <dependency>
+      <groupId>org.springframework.cloud</groupId>
+      <artifactId>spring-cloud-starter-gateway</artifactId>
+    </dependency>
+
+```
+
+* 在 application.yml 中，添加 spring.cloud.gateway.routes 配置
+
+```yaml
+spring:
+  cloud:
+    gateway:
+      routes:
+      - id: system-api
+        uri: http://localhost:8081
+        predicates:
+        - Path=/api/system/**
+        filters:
+        - RewritePath=/api/system/(?<suffix>.*), /$\{suffix}
+      - id: biz-api
+        uri: http://localhost:8081
+        predicates:
+        - Path=/api/biz/**
+        filters:
+        - RewritePath=/api/biz/(?<suffix>.*), /$\{suffix}
+
+```
+
+**疑问？为何不用服务注册与发现**
+
+考虑到，后期部署采用 k8s，而 k8s 会提供服务注册与发现的能力，所以此处不再考虑
+
+若存在脱离 k8s 部署的情况，可以考虑采用 nginx 实现服务端负载均衡即可，或其他方案
+
+
+#### 远程调用
+
+远程调用的方式，基于 spring-cloud-openfeign 实现
+
+* 在 pom.xml 中，添加依赖配置
+
+```xml
+    <dependency>
+      <groupId>org.springframework.cloud</groupId>
+      <artifactId>spring-cloud-starter-openfeign</artifactId>
+    </dependency>
+
+```
+
+* 在 Application 中，添加注解 `@EnableFeignClients`，`@EnableSimpleUserTransmit`
+
+注解 `@EnableFeignClients`，表示启用 FeignClients 的配置
+
+注解 `@EnableSimpleUserTransmit`，表示将 后端的登录用户信息，在请求 服务接口 的过程中，进行传递（加入到请求头 Header 中）
+
+* 在 application.yml 中，添加 服务接口地址 配置
+
+如：
+```yml
+sw-backend-biz-api.uri: http://localhost:8081
+```
+
+* 在 remote 包 下，创建 FeignClient 类、FallbackFactory 类
+
+```java
+package com.supwisdom.institute.backend.admin.bff.apis.remote.biz;
+
+import org.springframework.cloud.openfeign.FeignClient;
+import org.springframework.web.bind.annotation.PathVariable;
+import org.springframework.web.bind.annotation.RequestBody;
+import org.springframework.web.bind.annotation.RequestMapping;
+import org.springframework.web.bind.annotation.RequestMethod;
+import org.springframework.web.bind.annotation.RequestParam;
+
+import com.alibaba.fastjson.JSONObject;
+import com.supwisdom.institute.backend.admin.bff.apis.model.biz.Biz;
+
+@FeignClient(
+    name = "biz-biz-remote-feign-client",
+    url = "${sw-backend-biz-api.uri}/v1/admin/biz",
+    fallbackFactory = BizRemoteFallbackFactory.class
+)
+public interface BizRemoteFeignClient {
+  
+  @RequestMapping(method = RequestMethod.GET)
+  JSONObject query(
+      @RequestParam(name = "loadAll") boolean loadAll,
+      @RequestParam(name = "pageIndex") int pageIndex,
+      @RequestParam(name = "pageSize") int pageSize
+      
+  );
+  
+  @RequestMapping(method = RequestMethod.GET, path = "/{id}")
+  JSONObject load(
+      @PathVariable(name = "id") String id
+  );
+
+  @RequestMapping(method = RequestMethod.POST)
+  JSONObject create(
+      @RequestBody Biz biz
+  );
+
+  @RequestMapping(method = RequestMethod.PUT, path = "/{id}")
+  JSONObject update(
+      @PathVariable(name = "id") String id,
+      @RequestBody Biz biz
+  );
+  
+  @RequestMapping(method = RequestMethod.DELETE, path = "/{id}")
+  JSONObject delete(
+      @PathVariable(name = "id") String id
+  );
+
+}
+
+```
+
+注解 `@FeignClient`，`url` 指定后端服务的地址，`fallbackFactory` 指定熔断回调处理的工厂类
+
+```java
+package com.supwisdom.institute.backend.admin.bff.apis.remote.biz;
+
+import org.springframework.stereotype.Component;
+
+import com.alibaba.fastjson.JSONObject;
+import com.supwisdom.institute.backend.admin.bff.apis.model.biz.Biz;
+import com.supwisdom.institute.backend.admin.bff.remote.FallbackError;
+
+import feign.hystrix.FallbackFactory;
+
+@Component
+public class BizRemoteFallbackFactory implements FallbackFactory<BizRemoteFeignClient> {
+
+  @Override
+  public BizRemoteFeignClient create(Throwable cause) {
+    return new BizRemoteFeignClient() {
+
+      @Override
+      public JSONObject query(boolean loadAll, int pageIndex, int pageSize) {
+        if (cause != null) {
+          cause.printStackTrace();
+        }
+        return FallbackError.defaultErrorJson(cause);
+      }
+
+      @Override
+      public JSONObject load(String id) {
+        if (cause != null) {
+          cause.printStackTrace();
+        }
+        return FallbackError.defaultErrorJson(cause);
+      }
+
+      @Override
+      public JSONObject create(Biz biz) {
+        if (cause != null) {
+          cause.printStackTrace();
+        }
+        return FallbackError.defaultErrorJson(cause);
+      }
+
+      @Override
+      public JSONObject update(String id, Biz biz) {
+        if (cause != null) {
+          cause.printStackTrace();
+        }
+        return FallbackError.defaultErrorJson(cause);
+      }
+
+      @Override
+      public JSONObject delete(String id) {
+        if (cause != null) {
+          cause.printStackTrace();
+        }
+        return FallbackError.defaultErrorJson(cause);
+      }
+
