将JSON对象发送到Spring POST控制器

I am trying to send a JSON object by AJAX to a Spring controller but receive an error 415:

我试图通过AJAX将一个JSON对象发送到Spring控制器,但收到错误415:

"The server refused this request because the request entity is in a format not supported by the requested resource for the requested method."

“服务器拒绝了此请求,因为请求实体的格式不受所请求方法所请求资源的支持。”

My Spring controller looks like this and is running on Tomcat 7 -

我的Spring控制器看起来像这样并且在Tomcat 7上运行 -

@RequestMapping(
    value = "/ab/greeting", 
    method=RequestMethod.POST, headers = "Accept=*/*",
    produces = "application/json")
public String greetingSubmit(@RequestBody Person p1) {
    return "result";
}

The Person class is defined like this -

Person类定义如下 -

package ab;

public class Person {

    String fname;
    String lname;
} 

Here is my javascript making the call -

这是我的javascript打电话 -

function getGreeting() {
        $.ajax({
            url : "/ab/greeting",
            contentType: "application/json",
            type: 'POST',
            async: false,
            data: JSON.stringify({ fname: "John", lname: "Doe" }),
            success: function (data) {
            }
        });
    }

Here are my dependencies Jackson related dependencies in my POM -

以下是我在POM中与杰克逊相关的依赖关系 -

<dependency>
            <groupId>org.codehaus.jackson</groupId>
            <artifactId>jackson-mapper-asl</artifactId>
        </dependency>

        <dependency>
            <groupId>org.codehaus.jackson</groupId>
            <artifactId>jackson-core-asl</artifactId>
        </dependency>

Ironically, it works when I try it on Spring Boot.

具有讽刺意味的是,当我在Spring Boot上尝试时,它可以工作。

On Tomcat, I have also tried using @ModelAttribute in place of @RequestBody - in which case, the request returns with a error code 200 but the p1 object comes out null in the controller.

在Tomcat上,我也尝试使用@ModelAttribute代替@RequestBody - 在这种情况下,请求返回错误代码200,但p1对象在控制器中出现null。

Is this related to the difference between Spring and Spring MVC? - apologies for the noob question. My controller class is annotated only with @Controller.

这与Spring和Spring MVC之间的区别有关吗? - 为noob问题道歉。我的控制器类仅使用@Controller进行注释。

How do I modify this to be able to send a JSON object from AJAX to Spring POST controller? Eventually, I would like to send an array of 5 objects.

如何修改此能够将AJSON中的JSON对象发送到Spring POST控制器?最后,我想发送一个包含5个对象的数组。

Please help.

Thanks

Add the consumes attribute

添加consumemes属性

@RequestMapping(value = "/ab/greeting", method=RequestMethod.POST,headers = "Accept=*/*",produces = "application/json", consumes="application/json")
public String greetingSubmit(@RequestBody Person p1) {
    return "result";
}
