这个报错的原因是我们的Controller中,有两个模棱两可的处理方法,这两个方法有歧义,无法分清谁是谁.因为Spring无法根据传参的类型自动匹配到可以处理的方法。比如下面这里,
@GetMapping("/{id}")和
@GetMapping("/{addr}")是冲突的,必须修改一下其中的一个url区分开来
package com.xzit.controller; import com.github.pagehelper.PageHelper; import com.github.pagehelper.PageInfo; import com.xzit.entity.Emp; import com.xzit.service.EmpService; import io.swagger.annotations.Api; import io.swagger.annotations.ApiModelProperty; import io.swagger.annotations.ApiOperation; import org.springframework.web.bind.annotation.*; import javax.annotation.Resource; import java.util.List; @RestController @RequestMapping("emp") @Api(tags = {"员工管理控制器"}) public class EmpController { @Resource private EmpService service; @ApiOperation("按给定的id显示员工信息") @GetMapping("/{id}") public Object selectId(@PathVariable Integer id){ Emp emp=service.selectId(id); return emp; } @ApiOperation("按给定地址查询员工信息") @GetMapping("/{addr}") public Object selectAddr(@PathVariable String addr){ List<Emp> empList=service.selectAddr(addr); return empList; } }
执行的报错信息,它分不清这两个方法。
正确的修改方式,我在selecAddr()方法随便加一个/userAddr的Url前缀:
package com.xzit.controller; import com.github.pagehelper.PageHelper; import com.github.pagehelper.PageInfo; import com.xzit.entity.Emp; import com.xzit.service.EmpService; import io.swagger.annotations.Api; import io.swagger.annotations.ApiModelProperty; import io.swagger.annotations.ApiOperation; import org.springframework.web.bind.annotation.*; import javax.annotation.Resource; import java.util.List; @RestController @RequestMapping("emp") @Api(tags = {"员工管理控制器"}) public class EmpController { @Resource private EmpService service; @ApiOperation("按给定的id显示员工信息") @GetMapping("/{id}") public Object selectId(@PathVariable Integer id){ Emp emp=service.selectId(id); return emp; } @ApiOperation("按给定地址查询员工信息") @GetMapping("/userAddr/{addr}") public Object selectAddr(@PathVariable String addr){ List<Emp> empList=service.selectAddr(addr); return empList; } }
重启服务,报错解决,可以正确查询出数据了:
