第一步:创建一个Maven工程。加入Jersey、Spring、Jersey+Spring的依赖包,以及内嵌的Tomcat7插件;

pom.xml文件如图所示:

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>com.zte.ems</groupId>
  <artifactId>jersey-spring</artifactId>
  <packaging>war</packaging>
  <version>0.0.1-SNAPSHOT</version>
  <name>jersey-spring Maven Webapp</name>
  <url>http://maven.apache.org</url>
   <dependencies>
        <!-- Jersey  -->
        <dependency>
            <groupId>com.sun.jersey</groupId>
            <artifactId>jersey-server</artifactId>
            <version>1.8</version>
        </dependency>

        <!-- Spring 3 dependencies -->
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-core</artifactId>
            <version>3.0.5.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-context</artifactId>
            <version>3.0.5.RELEASE</version>
        </dependency>
        <dependency>
            <groupId>org.springframework</groupId>
            <artifactId>spring-web</artifactId>
            <version>3.0.5.RELEASE</version>
        </dependency>

        <!-- Jersey + Spring -->
        <dependency>
            <groupId>com.sun.jersey.contribs</groupId>
            <artifactId>jersey-spring</artifactId>
            <version>1.8</version>
            <exclusions>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring-core</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring-web</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring-beans</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>org.springframework</groupId>
                    <artifactId>spring-context</artifactId>
                </exclusion>
            </exclusions>
        </dependency>
        <!-- 添加jsp、servlet依赖 -->
        <!-- servlet api -->  
        <dependency>  
            <groupId>javax.servlet</groupId>  
            <artifactId>javax.servlet-api</artifactId>  
            <version>3.0.1</version>  
            <scope>provided</scope>  
        </dependency>  
        <!-- jstl -->  
        <dependency>  
            <groupId>javax.servlet</groupId>  
            <artifactId>jstl</artifactId>  
            <version>1.2</version>  
        </dependency>  
        <dependency>
            <groupId>taglibs</groupId>
            <artifactId>standard</artifactId>
            <version>1.1.2</version>
        </dependency>
    </dependencies> 
  <build>
    <finalName>jersey-spring</finalName>
    <pluginManagement>
        <plugins>
            <plugin>
            <!-- 配置tomcat7插件 -->
            <groupId>org.apache.tomcat.maven</groupId>
             <artifactId>tomcat7-maven-plugin</artifactId>
              <version>2.2</version>
                <configuration>
                    <path>/jersey-spring</path>
                    <port>8080</port>
                    <uriEncoding>UTF-8</uriEncoding>
                    <url>http://localhost:8080/manager/text</url>
                    <server>tomcat7</server>
                </configuration>
            </plugin>
        </plugins>
    </pluginManagement>
  </build>
</project>

 

第二步:Spring配置文件的创建:很简单,就是添加需要扫描的基本包名

spring-context.xml文件如下所示:

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:context="http://www.springframework.org/schema/context"
    xsi:schemaLocation="http://www.springframework.org/schema/beans
    http://www.springframework.org/schema/beans/spring-beans-3.0.xsd 
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context-3.0.xsd">
    <context:component-scan base-package="com.zte.ems.*" />
    <context:annotation-config/>
</beans>

 

第三步:配置web.xml文件:主要是配置spring和spring+jersey的相关信息;

web.xml文件如下:

<!DOCTYPE web-app PUBLIC
 "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
 "http://java.sun.com/dtd/web-app_2_3.dtd" >
<web-app>
  <display-name>Archetype Created Web Application</display-name>
  <!-- 配置Spring -->
  <listener>
        <listener-class>
        org.springframework.web.context.ContextLoaderListener
        </listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-*.xml</param-value>
    </context-param>
  <!-- 配置Jersey+Spring -->
    <servlet>
        <servlet-name>jersey-serlvet</servlet-name>
        <servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>
        <init-param>
            <param-name>com.sun.jersey.config.property.packages</param-name>
            <param-value>com.zte.ems.resource</param-value>
        </init-param>
        <load-on-startup>1</load-on-startup>
    </servlet>
    <servlet-mapping>
        <servlet-name>jersey-serlvet</servlet-name>
        <url-pattern>/*</url-pattern>
    </servlet-mapping>
</web-app>

其中  <servlet-class>com.sun.jersey.spi.spring.container.servlet.SpringServlet</servlet-class>这一句常常出错,需要多注意。

第四步:写rest资源类

在com.zte.ems.resource包下添加一个StudentResource.java类,代码如下:

package com.zte.ems.resource;

import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;

import com.zte.ems.pojo.Student;
import com.zte.ems.service.StudentService;
@Component
@Path("/index")
public class StudentResource {
@Autowired
StudentService studentService;
@GET
@Produces({MediaType.APPLICATION_JSON,MediaType.APPLICATION_ATOM_XML})
@Path("/student")
public String getStudent(){
    return "hello Student!";
    }
}

@Component:表示这个类由Spring的IoC容器来管理,SpringMVC中使用的@Controller;

@AutoWired:表示Spring的自动装配,将需要依赖的类直接装配进来,当然本例子没有使用到,具体项目中一定会需要;

@Path("/index"):该注解标记在类名之上,表示这是一个根资源;类似于SpringMVC中的@RequestMapping("/index");

@Path("/student"):该注解标记在方法名之上,表示这是一个子资源,通过/student来寻找具体方法调用;

@GET:该注解表示被标记的方法提供的是一个GET请求,同样还有@POST、@PUT、@DELET、@PUTCH等注解;

@Produces({MediaType.xxx}):该注解表示以json或者xml文件的形式进行输出,类似于SpringMVC中的@ResponseBody注解;

当然还有@QueryParam,@Context等等注解,后面会专门写一篇关于Jersey和SpringMVC之间区别和联系的文章,敬请期待。

最后:

鼠标放在项目名上右击,Run As  ----> Maven build  ---->在Goals中输入clean tomcat7:run启动Tomcat服务器,然后在浏览器中输入http://localhost:8080/jersey-spring/index/student 弹出下图所示的成功界面:

到此为止,基于Jersey+Spring+Maven集成的简单框架搭建起来了。
