Question

我遇到以下代码的问题： 415不支持的MEDIA类型且服务器拒绝此请求，因为请求实体的格式不支持用于post方法。

随处搜索并做了所有事情但没有结果。

帮助!!

以下是主要代码

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;
    }
}

User.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) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
}

问题是您的方法参数类型cargo build --verbose Updating registry `https://github.com/rust-lang/crates.io-index` error Unable to update registry https://github.com/rust-lang/crates.io-index Caused by: [2/-1] Could not open '.cargo/registry/index/github.com-88ac128001ac3a9a/bi/tt/bittorrent' for writing: Access is denied.

MultivaluedHashMap

处理public Activity createActivityParams(MultivaluedHashMap<String, String> formse){和application/x-www-form-urlencoded的提供商仅支持MultivaluedMap或MultivaluedMap次注入。您可以在the source code

中看到

MultivaluedMap<String, String>

所以只需将方法参数更改为@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)); }

即可

java jersey中415不支持的媒体类型

Activity.java

User.java
