open-feign在两个模块之间的调用

sys模块定义生成者接口

test模块定义实体类对象、feign和fallback

package com.np.pm.test.model;

import com.baomidou.mybatisplus.annotation.TableField;
import com.np.pm.common.repository.model.system.SysMenu;
import io.swagger.annotations.ApiModelProperty;

import java.util.Date;
import java.util.List;
import java.util.Set;

/**

@Data
public class SysMenusVo {

    /**
     * 菜单/按钮ID
     */
    private Long id;

    /**
     * 上级菜单ID
     */
    private Long parentId;

    /**

    private Integer sortId;

    /**

    private Date createTime;

    /**

    private Date updateTime;

    /**

    @ApiModelProperty(value = "是否绑定权限")

    @ApiModelProperty(value = "keyword")
    private String keyword;

    /**
     * ORG_ID
     */
    @ApiModelProperty(value = "ORG_ID")
    private Long orgId;

    /**
     * 创建人ID
     */
    @ApiModelProperty(value = "创建人ID")
    //@ExcelProperty(value = "创建人ID", index = 3)
    private Long createHumId;

    /**
     * 创建人姓名
     */
    @ApiModelProperty(value = "创建人姓名")
    //@ExcelProperty(value = "创建人姓名", index = 5)
    private String createHumCode;

    /**
     * 创建人员姓名
     */
    @ApiModelProperty(value = "创建人员姓名")
    //@ExcelProperty(value = "创建人员姓名", index = 6)
    private String createHumName;

    /**
     * 部门ID
     */
    @ApiModelProperty(value = "部门ID")
    private Long deptId;

    /**
     * 打开方式（0组件 1NAV 2内链 3外链）
     */
    @ApiModelProperty(value = "打开方式（0组件 1NAV 2内链 3外链）")
    private Integer openType;

    @TableField(exist = false)
    private List<SysMenu> children;

    @TableField(exist = false)
    private Long roleId;

    @TableField(exist = false)
    private Set<Long> menuIds;
}

@FeignClient(value = ServiceNameConstant.SYSTEM_SERVICE, fallbackFactory = SystemServiceFallbackFactory.class)
public interface SystemService {

    /**
     * 查询菜单详情
     */
    @GetMapping("/sys/menu/{id}")
    Result<?> findById(@PathVariable(value = "id") Serializable id);

}

@Component
public class SystemServiceFallbackFactory implements FallbackFactory<SystemService> {


    @Override
    public SystemService create(Throwable cause) {
        return new SystemService() {
            @Override
            public Result<?> findById(Serializable id) {
                throw new ServiceException("查询失败");
            }
        };
    }

}

test-service使用

@Service
public class PmTestFormServiceImpl extends PMBaseTreeServiceImpl<PmTestFormMapper, PmTestForm> implements PmTestFormService {

    @Autowired
    private SystemService systemService;

    @Override
    public Result getMenuInfo(Long id) {
        Result<?> menuInfo = systemService.findById(id);
        if (!menuInfo.getFailed()) {
            SysMenusVo sysMenusVo = FastJsonUtil.copyProperty(menuInfo.getData(), SysMenusVo.class);
            return Result.success(sysMenusVo);
        } else {
            return Result.failure("查询失败");
        }
    }

}

结果
