Springmvc rest 传递json报415错误
报错如下：（The server refused this request because the request entity is in a format
not supported by the requested resource for the requested method.）
----------------------------------------------------------------------------------------------------------------------
解决：
1、后台代码：
（1）HelloController类
@RestController
@RequestMapping(value="/hello")
public class HelloController {
@RequestMapping(value = "/greeting", method = RequestMethod.POST,
consumes = "application/json")
@ResponseBody
public TeacherVO greeting(@RequestBody TeacherVO t) {
System.out.println(t.getName());
return t;
}
}
（2）TeacherVO类
public class TeacherVO {
private String id ;
private String name ;
private String age ;
public TeacherVO(){
}
public TeacherVO(String id, String name, String age) {
super();
this.id = id;
this.name = name;
this.age = age;
}
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getAge() {
return age;
}
public void setAge(String age) {
this.age = age;
}
}
2、项目类路径需包含json类库，jackson-databind-2.7.5.jar、jackson-annotations-2.7.0.jar及jackson-core-2.7.5.jar。
3、项目配置文件中应包含<mvc:annotation-driven />，即启用了注解识别。
4、确保post man访问时设置了header中的Content-Type值为application/json。
再次使用post man访问，则可以正常访问了。
