3.java代码
Login.java
package controller;
import controller.vo.User;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
@RestController
@RequestMapping(value = "/sdkapp")
public class Login {
@RequestMapping(value = "/init")
public ModelAndView casdkbindInput(){
ModelAndView view = new ModelAndView("/login");
return view;
}
@RequestMapping(value = "/login",method = {RequestMethod.POST},consumes = "application/json;charset=utf-8")
public ModelAndView testJson(@RequestBody User user) throws Exception {
System.out.println(user);
ModelAndView view = new ModelAndView("/success");
return view;
}
}
vo/User.java
package controller.vo;
import java.io.Serializable;
public class User implements Serializable {
private String uid;
private String username;
private String password;
public String getUid() {
return uid;
}
public void setUid(String uid) {
this.uid = uid;
}
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;
}
@Override
public String toString() {
return "User{" +
"uid='" + uid + '\'' +
", username='" + username + '\'' +
", password='" + password + '\'' +
'}';
}
}
问题是 jq post请求到后台，后台返回 view时，前端接收不到？
