使用Jersey的两种方式

Jersey可以较好地构建Rest API服务，特别在当前多客户端，一个服务端的情况下，使用API向手机端和网页端提供服务，关于Jersey的介绍可以参见：https://jersey.java.net，Jersey在Project使用时有两种jar实现，一种是使用sun的jar，一种是使用glassfish的jar。

在web.xml中的配置：

<!-- jersey web service -->
    <servlet>
        <servlet-name>Jersey Web Application</servlet-name>
        <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>jersey.config.server.provider.packages</param-name>
            <param-value>com.exam.handler</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey Web Application</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
    

    <servlet>
        <servlet-name>Jersey REST Service</servlet-name>
        <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
        <init-param>
            <param-name>com.sun.jersey.config.property.packages</param-name>
            <param-value>com.exam.handler</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>Jersey REST Service</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>

在Maven工程的pom.xml文件配置：

<!-- Jersey core Servlet 3.x implementation
    <dependency>
      <groupId>org.glassfish.jersey.containers</groupId>
      <artifactId>jersey-container-servlet</artifactId>
      <version>2.17</version>
    </dependency>
    -->
    <!-- Jersey core Servlet 2.x implementation
    <dependency>
      <groupId>org.glassfish.jersey.containers</groupId>
      <artifactId>jersey-container-servlet-core</artifactId>
      <version>2.5</version>
    </dependency>
    -->
    <!-- sun jersey servlet -->
    <dependency>
      <groupId>com.sun.jersey</groupId>
      <artifactId>jersey-servlet</artifactId>
      <version>1.19</version>
    </dependency>
