Spring+CXF开发RESTful风格的WebService

Spring+CXF开发RESTful风格的WebService

使用apache-cxf-2.7.18版本的cxf相关jar包

项目结构图：



StudentBean.java

package com.zxj.webservice.beans;

import java.io.Serializable;

import javax.xml.bind.annotation.XmlRootElement;

@XmlRootElement(name="student")
public class StudentBean implements Serializable {

private static final long serialVersionUID = 1L;

private long id;
private String name;

public StudentBean() {
super();
}

public long getId() {
return id;
}

public void setId(long id) {
this.id = id;
}

public String getName() {
return name;
}

public void setName(String name) {
this.name = name;
}

@Override
public String toString() {
return "StudentBean [id=" + id + ", name=" + name + "]";
}

}

服务接口：IStudentWebService.java

package com.zxj.webservice.studentserver;

import java.util.List;

import javax.jws.WebService;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
import javax.ws.rs.PathParam;
import javax.ws.rs.Produces;
import javax.ws.rs.core.MediaType;

import com.zxj.webservice.beans.StudentBean;

@WebService
@Path("/student")
public interface IStudentWebService {

@Path("/getstudent/{id}")
//指定JSON数据类型
@Produces("application/json;charset=utf-8")
@GET
public StudentBean getStudent(@PathParam("id") long id);

@Path("/getstudents/{name}")
//指定XML数据类型
@Produces(MediaType.APPLICATION_XML)
@GET
public List<StudentBean> getStudents(@PathParam("name") String name);
}

服务接口实现类：StudentWebServerImpl.java

package com.zxj.webservice.studentserver.impl;

import java.util.ArrayList;
import java.util.List;

import com.zxj.webservice.beans.StudentBean;
import com.zxj.webservice.studentserver.IStudentWebService;

public class StudentWebServerImpl implements IStudentWebService {

@Override
public StudentBean getStudent(long id) {
StudentBean student = new StudentBean();
student.setId(id);
student.setName("赵祥军");
return student;
}

@Override
public List<StudentBean> getStudents(String name) {
List<StudentBean> students = new ArrayList<StudentBean>();
StudentBean student1 = new StudentBean();
student1.setId(1);
student1.setName(name);
StudentBean student2 = new StudentBean();
student2.setId(2);
student2.setName("XiangjunZhao");
students.add(student1);
students.add(student2);
return students;
}

}
