SpringBoot项目与项目之间简单流程

发表于 | 分类于

简单总结一下SpringBoot项目与项目之间简单流程，以获取字典为例，不谈论实现代码，只说流程跳转

过程

  • 首先是consume模块（服务消费），在controller层定义

@RestController
@RequestMapping(value = "/dcDic")
public class DcDicController {

 	@Autowired
    DcOrgService dcOrgService;

// 获取行政区字典
    @PostMapping("/getArea")
    public ResultMsg<Dictionary> getArea(@RequestBody DcOrgParam dcOrgParam) {

        List<DcOrg> list = dcOrgService.getList(dcOrgParam);

        // 填充字典
        Dictionary dictionary = new Dictionary();
        dictionary.fillBy(list);

        return ResultMsg.ok(dictionary);

    }
}
  • 然后在consume模块的Service层定义(这层主要是将接口暴露给consume的controller)

@FeignClient(value = "service-groundNet")
public interface DcOrgService {

    @PostMapping("/dcOrg/getList")
    List<DcOrg>getList(@RequestBody DcOrgParam dcOrgParam);
}
  • 在provider模块的controller层，需要定义一个和上面一样的URL

@RestController
@RequestMapping(value = {"/dcOrg"})
public class DcOrgController {

    @Autowired
    DcOrgRepository dcOrgRepository;
	// 这儿定义的url要和consume模块的Service层一样
    @PostMapping("/getList")
    public List<DcOrg> getList(@RequestBody DcOrgParam dcOrgParam) {
        return dcOrgRepository.getList(dcOrgParam);
    }
}
  • 在仓储层repository中定义方法（类似Service层）

package com.nb.xry.common.repository;

//父接口
public interface CrudRepository<E, PK> {

    void add(E e) throws Exception;

    void remove(PK id) throws Exception;

    void edit(E e) throws Exception;

    E get(PK id);
}

// 这里继承的是自定义的一个增删改查接口(子接口自动具有父接口的所有抽象数据和方法)
// 子接口
public interface DcOrgRepository extends CrudRepository<DcOrg,String> {
    List<DcOrg> getList(DcOrgParam dcOrgParam);
}
  • 定义仓储层repository的实现

@Repository
public class DcOrgRepositoryImpl implements DcOrgRepository {

    @Autowired
    DcOrgMapper dcOrgMapper;

    @Override
    public void add(DcOrg dcOrg) throws Exception {

    }

    @Override
    public void remove(String id) throws Exception {

    }

    @Override
    public void edit(DcOrg dcOrg) throws Exception {

    }

    @Override
    public DcOrg get(String id) {
       
    }

    @Override
    public List<DcOrg> getList(DcOrgParam dcOrgParam) {
        return dcOrgMapper.getList(dcOrgParam);
    }
}
  • 定义Mapper接口

@Mapper
public interface DcOrgMapper {
 
    List<DcOrg> getList(DcOrgParam dcOrgParam);
}
  • 最后写mybaits的Mapper.xml

<select id="getList" parameterType="com.nb.xry.groundnet.param.DcOrgParam" resultMap="BaseResultMap">
    SELECT ID, NAME, ADDRESS, UID, TYPE, SHORTNAME, CSSSTYLE, SEQ, isdelete, createtime, updatetime,
    orgcode, importName, districtCode, wgType, dc_datastate, dc_insertTime, isChange,content
    FROM dc_grid_org_org
    <where>
        <if test="level != null and level != 0">
            and type = #{level}
        </if>
        <if test="parentUid != null and parentUid != '' ">
            and uid like CONCAT(#{parentUid},'%')
        </if>
    </where>
</select>
