這里面用的是jersey
1. 創(chuàng)建一個(gè)project
2. 建立返回的model
這里面的model例子

注意:
Using Entity Providers to Map HTTP Response and Request Entity Bodies
Entity providers supply mapping services between representations and their associated Java types. There are two types of entity providers: MessageBodyReader and MessageBodyWriter. For HTTP requests, the MessageBodyReader is used to map an HTTP request entity body to method parameters. On the response side, a return value is mapped to an HTTP response entity body using a MessageBodyWriter. If the application needs to supply additional metadata, such as HTTP headers or a different status code, a method can return a Response that wraps the entity, and which can be built using Response.ResponseBuilder.
The following list contains the standard types that are supported automatically for entities. You only need to write an entity provider if you are not choosing one of the following, standard types.
byte[] — All media types (*/*)
java.lang.String — All text media types (text/*)
java.io.InputStream — All media types (*/*)
java.io.Reader — All media types (*/*)
java.io.File — All media types (*/*)
javax.activation.DataSource — All media types (*/*)
javax.xml.transform.Source — XML types (text/xml, application/xml and application/*+xml)
javax.xml.bind.JAXBElement and application-supplied JAXB classes XML media types (text/xml, application/xml and application/*+xml)
MultivaluedMap<String, String> — Form content (application/x-www-form-urlencoded)
StreamingOutput — All media types (*/*), MessageBodyWriter only
3.創(chuàng)建resources

4.修改web.xml
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">
<servlet>
<servlet-name>ServletAdaptor</servlet-name>
<servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
<servlet-mapping>
<servlet-name>ServletAdaptor</servlet-name>
<url-pattern>/*</url-pattern>
</servlet-mapping>
<session-config>
<session-timeout>
30
</session-timeout>
</session-config>
<welcome-file-list>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>
</web-app>
注意：需要的jar
aopalliance.jar ;jersey-core-1.1.0-ea.jar;asm-3.1.jar ;jersey-json-1.1.2-ea.jar ;aspectjrt-1.5.4.jar;jersey-server-1.1.0-ea.jar ;aspectjweaver-1.5.4.jar ; jersey-spring-1.1.0-ea.jar; spring-2.5.6.jar;cglib-2.2.jar ; jsr311-api-1.1.jar ;
