我正在尝试将JSON数据发送到我的RESTful Web服务。对于简单的GET类型,配置工作正常。只有问题是POST类型。
我的角色代码
var app = angular.module('myApp', []);
app.controller('MyController', function($scope,$http) {
$scope.pushDataToServer = function() {
$http({
method: 'POST',
url: 'rest/Board/autoSave',
headers: {'Content-Type': 'application/json'},
data:'{"firstName":"Syed", "lastName":"Chennai"}',
}).success(function (data){
$scope.status=data;
}).error(function(data, status, headers, config) {
alert("error");
});
};
});
@Path("/Board")
public class BoardAutoSaveService {
@POST
@Path("/autoSave")
@Consumes({MediaType.APPLICATION_JSON})
@Produces({MediaType.TEXT_PLAIN})
public String autoSave(Message msg) throws Exception{
System.out.println("Calling Autosave.");
System.out.println("First Name = "+msg.getFirstName());
System.out.println("Last Name = "+msg.getLastName());
return null;
}
}
package com.intu;
import java.util.Date;
public class Message {
private String firstName;
private String lastName;
private int age;
private Date date;
private String text;
public String getFirstName() {
return firstName;
}
public void setFirstName(String firstName) {
this.firstName = firstName;
}
public String getLastName() {
return lastName;
}
public void setLastName(String lastName) {
this.lastName = lastName;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public Date getDate() {
return date;
}
public void setDate(Date date) {
this.date = date;
}
public String getText() {
return text;
}
public void setText(String text) {
this.text = text;
}
}

我错过了什么吗?
错误是
SEVERE: A message body reader for Java class com.intu.Message, and Java type class com.intu.Message, and MIME media type application/json was not found.
The registered message body readers compatible with the MIME media type are:
application/json ->
com.sun.jersey.json.impl.provider.entity.JSONJAXBElementProvider$App
com.sun.jersey.json.impl.provider.entity.JSONRootElementProvider$App
com.sun.jersey.json.impl.provider.entity.JSONListElementProvider$App
*/* ->
答案 0 :(得分:0)
您只有默认的Jersey JSON提供程序,在您的模型类上需要@XmlRootElement
。您可以看到可用的提供商,其中一个是JSON**RootElement**Provider
com.sun.jersey.json.impl.provider.entity.JSONJAXBElementProvider$App
com.sun.jersey.json.impl.provider.entity.JSONRootElementProvider$App
com.sun.jersey.json.impl.provider.entity.JSONListElementProvider$App
此提供程序用于(de)序列化使用@XmlRootElement
注释的类。
如果您有以下依赖
<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-json</artifactId>
<version>${jersey.version}</version>
</dependency>
然后它还应该提供杰克逊提供商,它不需要@XmlRootElement
,但你仍然需要配置泽西岛使用杰克逊而不是默认提供商。要配置它,您需要将其添加到web.xml Jersey servlet配置中,如here 所示
<init-param>
<param-name>com.sun.jersey.api.json.POJOMappingFeature</param-name>
<param-value>true</param-value>
</init-param>
或者如果您没有使用web.xml,请在ResourceConfig
子类构造函数中添加以下内容
public class AppConfig extends PackagesResourceConfig{
public AppConfig() {
getProperties().put(JSONConfiguration.FEATURE_POJO_MAPPING, true);
}
}
