• 方法一：利用ajax， 並設定contentType: ‘application/json’ （必須要設定，@RequestBody需要根據這個來確定需要使用jsonHttpMessageCon） ，後臺用@RequestBody接受前臺傳遞的json字串

--jsp頁面
function submitFrom1 () {
          var list = [];
          for (var i = 0 ; i < 3 ; i++) {
              var params = {};
              params['pkg_id'] = "123_"
 
 + i;
              params['pkg_name'] = "1234_" + i;
              params['pkg_desc'] = "1235_" + i;
              list.push(params);
          }
          $("#jsonParams").val(JSON.stringify(list));
          $.ajax ({
              type:'post',
                 time:20000,
                 contentType: 'application/json'
 
,
                 dateType:'json',
                 url:$("#contextPath").val()+'/bigPackage/test.do',
                 data:JSON.stringify(list),
                 success:function(data){
                     alert(data);
                 },
                 error:function(e){
                 }
          });
      }
--controller層：
@RequestMapping("test")
 

    @ResponseBody
    public String test (@RequestBody BigPackageVO [] vo) {
        for (BigPackageVO v : vo) {
            String pkg_id = v.getPkg_id();
            String pkg_name = v.getPkg_name();
            String pkg_desc = v.getPkg_desc() ;
            log.info("pkg_id:" + pkg_id + "pkg_name:" + pkg_name + "pkg_desc:" + pkg_desc);
        }
        return "0" ;
    }

• 方法2：

--jsp頁面
<form action="<%=basePath%>bigPackage/test1.do" method="post" id="testForm">
        <input type="text" name="list[0].username" value="user1"><br/>
        <input type="text" name="list[0].password" value="pwd1"><br/>
        <input type="text" name="list[1].username" value="user2"><br/>
        <input type="text" name="list[1].password" value="pwd2"><br/>
        <input type="button" value="submit" onclick="formSubmit();"/>
    </form>
--controller層：
@RequestMapping("test1")
    public void test1 (UserModel u) {
        List<User> list = u.getList();
        for (User user : list) {
            log.info(user.getUsername());
        }
    }
--User類
public class User {
    private String username;
    private String password;
    public String getUsername() {
        return username;
    }
    public void setUsername(String username) {
        this.username = username;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }

}
--UserModel類
public class UserModel {
    private List<User> list;

    public List<User> getList() {
        return list;
    }

    public void setList(List<User> list) {
        this.list = list;
    }
}

–注意


兩者必須相同
