Java Rest WebService 三步服务发布

本Markdown编辑器使用[StackEdit][6]修改而来，用它写博客，将会带来全新的体验哦：

• 使用Idea开发工具创建Maven项目
• 在pom.xml中加载库文件
• 主要Java代码
• 修改web.xml

---

1.使用Idea开发工具创建Maven项目,省略

2.在pom.xml中加载库文件

<properties><project.build.sourceEncoding>UTF-8</project.build.sourceEncoding><project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding><encoding>UTF-8</encoding><cxf.version>3.1.7</cxf.version><spring.version>4.1.4.RELEASE</spring.version>  </properties>  <dependencies><!--这是rs框架的包-->    <dependency>      <groupId>javax.ws.rs</groupId>      <artifactId>jsr311-api</artifactId>      <version>1.1</version>    </dependency><!--这是cxf框架的包--><dependency>  <groupId>org.apache.cxf</groupId>  <artifactId>cxf-rt-frontend-jaxrs</artifactId>  <version>${cxf.version}</version></dependency><dependency>  <groupId>org.apache.cxf</groupId>  <artifactId>cxf-rt-transports-http</artifactId>  <version>${cxf.version}</version></dependency><dependency>  <groupId>org.codehaus.jackson</groupId>  <artifactId>jackson-mapper-asl</artifactId>  <version>1.9.2</version></dependency><dependency>  <groupId>org.codehaus.jackson</groupId>  <artifactId>jackson-jaxrs</artifactId>  <version>1.9.13</version></dependency><!--这是jersey框架的包--><dependency>  <groupId>com.sun.jersey</groupId>  <artifactId>jersey-client</artifactId>  <version>1.17.1</version></dependency><dependency>  <groupId>com.sun.jersey</groupId>  <artifactId>jersey-core</artifactId>  <version>1.17.1</version></dependency><dependency>  <groupId>com.sun.jersey</groupId>  <artifactId>jersey-server</artifactId>  <version>1.17.1</version></dependency><dependency>  <groupId>com.sun.jersey</groupId>  <artifactId>jersey-servlet</artifactId>  <version>1.17.1</version></dependency><!--这是asm框架的包--><dependency>  <groupId>asm</groupId>  <artifactId>asm</artifactId>  <version>3.3.1</version></dependency>

3.主要Java代码

接口：public interface StudentResource {    @POST    @Consumes(MediaType.APPLICATION_JSON)    public Response postStudent();    @GET    @Consumes(MediaType.APPLICATION_JSON)    public Response getStudent();    @Path("queryById/{id}")        public Response queryById(@PathParam("id")int id);}---------------------------------------------------------实现类：@Path("/resource")public class StudentResourceImpl implements StudentResource{/** * 一个简单的文本信息 * @return */public Response postStudent() {    System.out.println("===postStudent()===");    return Response.status(200).entity("Hello Student post !").build();}public Response getStudent() {    System.out.println("===getStudent()===");    return Response.status(200).entity("Hello Student get !").build();}public Response queryById(int id) {    System.out.println("===queryById()===");    return Response.status(200).entity("Hello Student queryById " + id + " !").build();}

}

4.修改web.xml

com.ttook.cxf.resource 把这个包下的class发布rest服务

JAX-RS-Servlet servlet名称
/cxf/* url访问方式
