Jersey-demo

这是个Jersey的domo项目

jersey version:2.25

1、再pom中加上依赖

    <dependencies>
        <dependency>
            <groupId>org.glassfish.jersey.containers</groupId>
            <artifactId>jersey-container-servlet</artifactId>
            <version>2.25</version>
        </dependency>
        <dependency>
            <groupId>org.glassfish.jersey.media</groupId>
            <artifactId>jersey-media-json-jackson</artifactId>
            <version>2.25</version>
        </dependency>
    </dependencies>

2、新建web.xml(src/main/resources/webapp/WEB-INF/web.xml)

<web-app>
    <servlet>
        <servlet-name>JerseyServletContainer</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>javax.ws.rs.Application</param-name>
            <param-value>cn.kevinw.config.RestApplication</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>JerseyServletContainer</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

3、在RestApplication.java中注册需要的组件

4、RestExceptionHandler.java统一处理exception，可以自定义responseCode等等

5、对request和response预处理 RestContainerRequestFilter.java RestContainerResponseFilter

6、对entity做处理，stream的形式 RestReaderInterceptor.java RestWriterInterceptor.java
