一、只接收一个List
1、form表单提交
controller代码
ResponseBody
RequestMapping(test)
public void test(RequestParam(valuelist,required false) ListInteger list) {for (Integer integer : list) {System.out.println(integer);}}postman 2、提交json对象
controller代码
ResponseBody
RequestMapping(test)public void test(RequestBody ListInteger list) {for (Integer integer : list) {System.out.println(integer);}}postman
请求头设置Content-Type application/json 总结一下
controller 的区别在接收参数注解不一样form表单提交是RequestParam接收json对象是RequestBody
二、同时接收List和StringInterger等其他参数
1、form表单提交
controller代码 ResponseBodyRequestMapping(test)public void test(RequestParam(valuelist,required false) ListInteger list,RequestParam(valuetest,required false) String test) {for (Integer integer : list) {System.out.println(integer);}System.out.println(test);}postman 2、接收json对象
controller代码 ResponseBodyRequestMapping(test)public void test(RequestBody TestList testList) {for (Integer integer : testList.getList()) {System.out.println(integer);}System.out.println(testList.getTest());}TestList 是自己写的接收对象
public class TestList {private ListInteger list;private String test;public ListInteger getList() {return list;}public void setList(ListInteger list) {this.list list;}public String getTest() {return test;}public void setTest(String test) {this.test test;}
}postman
请求Headers和之前一样 三、同时接收List、Map、String/Interger参数
controller代码
ResponseBody
RequestMapping(test)
public void test(RequestBody TestList testList) {for (Integer integer : testList.getList()) {System.out.println(integer);}System.out.println(testList.getTest());System.out.println(testList.getMap());
}pojo对象
public class TestList {private ListInteger list;private String test;private MapString, String map;public MapString, String getMap() {return map;}public void setMap(MapString, String map) {this.map map;}public ListInteger getList() {return list;}public void setList(ListInteger list) {this.list list;}public String getTest() {return test;}public void setTest(String test) {this.test test;}
}postman 接收成功 注POJO的传递和Map是一样的把“map”改成你的对象名称“ggg”这些换成对象的成员名称就可以了
四、接收List
controller: ResponseBodyRequestMapping(test)public void test(RequestBody ListPojoList list) {for (PojoList pojoList : list) {System.out.println(pojoList.getTest1());System.out.println(pojoList.getTest2());}}pojo:
public class PojoList {private String test1;private Integer test2;public String getTest1() {return test1;}public void setTest1(String test1) {this.test1 test1;}public Integer getTest2() {return test2;}public void setTest2(Integer test2) {this.test2 test2;}
}postman: 总结一下如果是单个List或者List带一些其他简单参数form表单提交和Json对象提交都差不多但是如果是比较复杂的数据组合个人建议建一个pojo去组合这些参数然后再去接收。希望能帮到大家如果有哪里不正确希望指正谢谢
