Maven和Jersey Framework开发REST风格Web Service

本文演示环境为eclipse + Maven插件 + Jersey framework。本文只关注Jersey的使用，所以只使用类中定义的静态数据做演示。请在使用时修改我的代码。如果你的eclipse中没有安装 Maven插件，请关注我的博客，我马上就会推出Maven+eclipse的开发教程。

1. 在eclipse中创建Maven项目

2.单击"Next"

3. 选择Maven项目类型为"maven-archetype-webapp"

4. 输入项目相关的Maven设置

5. 分别创建src/main下java文件夹以及src下test文件夹

6. 设置src/main/java和src/test/java为source folder

7. 最终设置结果如下：

8. 修改pom.xml,添加Maven相应依赖库

<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>net.jianxi.tutorials.jerseyws</groupId>    <artifactId>jerseywstest</artifactId>    <packaging>war</packaging>    <version>1.0</version>    <name>jerseywstest Maven Webapp</name>    <url>http://maven.apache.org</url>    <dependencies>        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <version>4.7</version>            <scope>test</scope>        </dependency>        <dependency>            <groupId>com.sun.jersey</groupId>            <artifactId>jersey-core</artifactId>            <version>1.3</version>        </dependency>        <dependency>            <groupId>com.sun.jersey</groupId>            <artifactId>jersey-server</artifactId>            <version>1.3</version>        </dependency>        <dependency>            <groupId>com.sun.jersey</groupId>            <artifactId>jersey-client</artifactId>            <version>1.3</version>        </dependency>        <dependency>            <groupId>log4j</groupId>            <artifactId>log4j</artifactId>            <version>1.2.14</version>        </dependency>        <dependency>            <groupId>javax.ws.rs</groupId>            <artifactId>jsr311-api</artifactId>            <version>1.1.1</version>        </dependency>        <dependency>            <groupId>asm</groupId>            <artifactId>asm</artifactId>            <version>3.2</version>        </dependency>    </dependencies>    <build>        <finalName>jerseywstest</finalName>        <plugins>            <plugin>                <artifactId>maven-compiler-plugin</artifactId>                <configuration>                    <source>1.6</source>                    <target>1.6</target>                </configuration>            </plugin>            <plugin>                <groupId>org.codehaus.mojo</groupId>                <artifactId>tomcat-maven-plugin</artifactId>                <configuration>                    <warFile>target/jerseywstest.war</warFile>                </configuration>            </plugin>        </plugins>    </build></project>

9. 添加基本POJO类Student:

package net.jianxi.tutorials.jerseyws.metadata; 2  3  import javax.xml.bind.annotation.XmlRootElement; 4  5 @XmlRootElement 6  public class Student { 7     private int id; 8     private String name; 9     private String dept;10     11     public int getId() {12         return id;13     }14     15     public Student() {16     }17     18     public Student(int id, String name, String dept) {19         super();20         this.id = id;21         this.name = name;22         this.dept = dept;23     }24     public void setId(int id) {25         this.id = id;26     }27     public String getName() {28         return name;29     }30     public void setName(String name) {31         this.name = name;32     }33     public String getDept() {34         return dept;35     }36     public void setDept(String dept) {37         this.dept = dept;38     }39     40 }41  

 

10. 添加一个REST web服务实现类RestWsDemo:
