你好 StackOverFlow(s)
我已经解决了这个问题超过 2 个小时了 这很简单
我正在尝试使用 $.ajax POST 调用将 JSON 对象发送到 Spring Controller
我正在使用 AngularJS,但这一点没问题
这是服务器和客户端的代码以及spring配置
提前致谢
查询:
$scope.push = function() {
$.ajax({
type: "PUT",
url:"rest/todo/greeting/",
data : {id:"1",title:"ajax",description:"ajax"},
dataType: "json",
contentType : "application/json",
success : function(data) {
$log.info(data)
}
})
}
弹簧控制器:
@Controller
@RequestMapping("/todo")
public class TodoController {
@RequestMapping(value = "/greeting", method = RequestMethod.PUT,consumes="application/json",produces="text/html")
public @ResponseBody String push(@RequestBody Todo todo) {
System.out.println(todo.getTitle());
return "test";
}
}
弹簧配置:
<mvc:annotation-driven />
<context:component-scan base-package="org.lab.todo.controller" />
<bean id="defaultViews" class="org.springframework.web.servlet.view.json.MappingJackson2JsonView" />

Ajax 调用更新:
$scope.push = function() {
var jsonString = {id:"1",title:"ajax",description:"ajax"};
var Todo = function(){}
Todo.id = "id";
Todo.title = "ajax";
Todo.description = "ajax";
$.post("rest/todo/greeting",JSON.stringify(Todo),function(response){console.log(response)},'json');
}
