将GET请求参数自动映射到POJO
我的REST控制器中有包含很多参数的方法。例如:
@RequestMapping(value = "/getItem", method = RequestMethod.GET)public ServiceRequest<List<SomeModel>> getClaimStatuses(
@RequestParam(value = "param1", required = true) List<String> param1,
@RequestParam(value = "param2", required = false) String param2,
@RequestParam(value = "param3", required = false) List<String> param3,
@RequestParam(value = "param4", required = false) List<String> param4,
@RequestParam(value = "param5", required = false) List<String> param5) {
// ......
}
而且我想将所有GET请求参数映射到POJO对象,例如:
public class RequestParamsModel { public RequestParamsModel() {
}
public List<String> param1;
public String param2;
public List<String> param3;
public String param4;
public String param5;
}
我需要像我们可以在REST Controller中使用@RequestBody一样的方法。
谢谢!

可能且容易,请确保您的bean对这些字段具有正确的访问器。您可以为每个属性添加适当的验证,只需确保已安装适当的jar即可。就代码而言,它将类似于
import javax.validation.constraints.NotNull;public class RequestParamsModel {
public RequestParamsModel() {}
private List<String> param1;
private String param2;
private List<String> param3;
private String param4;
private String param5;
@NotNull
public List<String> getParam1() {
return param1;
}
// ...
}
控制器方法为:
import javax.validation.Valid;@RequestMapping(value = "/getItem", method = RequestMethod.GET)
public ServiceRequest<List<SomeModel>> getClaimStatuses(@Valid RequestParamsModel model) {
// ...
}
和请求,例如:
/getItem?param1=list1,list2¶m2=ok
