下面是主要代码
ActivityResource.java
@Path("activityresource")
public class ActivityResource {
private ActivityRepo activityRepo=new ActivityRepositoryStub();
@POST
@Path("postActivity")
@Consumes(MediaType.APPLICATION_FORM_URLENCODED)
@Produces({MediaType.APPLICATION_XML,MediaType.APPLICATION_JSON})
public Activity createActivityParams(MultivaluedHashMap<String, String> formse){
System.out.println(formse.getFirst("discription"));
System.out.println(formse.getFirst("duration"));
Activity activity=new Activity();
activity.setDiscription(formse.getFirst("discription"));
activity.setDuration(Integer.parseInt(formse.getFirst("duration")));
activityRepo.create(activity);
return activity;
}
}
Activity.java
package com.ws.model;
import javax.xml.bind.annotation.XmlElement;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class Activity {
private String id;
private String discription;
private int duration;
private User user;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
@XmlElement(name="desc")
public String getDiscription() {
return discription;
}
public void setDiscription(String discription) {
this.discription = discription;
}
public int getDuration() {
return duration;
}
public void setDuration(int duration) {
this.duration = duration;
}
public User getUser() {
return user;
}
public void setUser(User user) {
this.user = user;
}
}
用户.java
package com.ws.model;
import javax.xml.bind.annotation.XmlRootElement;
@XmlRootElement
public class User {
private String id;
private String name;
public String getId() {
return id;
}
public void setId(String id) {

推荐答案
问题是你的方法参数类型 MultivaluedHashMap
The problem is your method parameter type MultivaluedHashMap
public Activity createActivityParams(MultivaluedHashMap<String, String> formse){
处理application/x-www-form-urlencoded和MultivaluedMap的提供者，只支持MultivaluedMap或MultivaluedMap
The provider that handle application/x-www-form-urlencoded and MultivaluedMap, only supports MultivaluedMap or MultivaluedMap<String, String> injections. You can see in the source code
@Override
public boolean isReadable(Class<?> type, Type genericType, Annotation[] annotations, MediaType mediaType) {
// Only allow types MultivaluedMap<String, String> and MultivaluedMap.
return type == MultivaluedMap.class
&& (type == genericType || mapType.equals(genericType));
}
所以只要把方法参数改成MultivaluedMap
So just change the method parameter to MultivaluedMap<String, String>
