cxf +spring+mybatis如何传输json数据并返回json数据

qq_24597963 2017-06-21 10:05:40

1. 设计一个查询学生信息的Restful服务，该服务的输入输出为Json格式的参数。其中输入参数为学号，输出参数为学生名字、性别、地址等基本信息
2.Restful服务的实现框架必须为CXF，接口格式为Json；

现在根据一个int学号能查出一个student对象的一个结果。

这是webservice接口

package com.sdo.webservice.webservice;



import javax.jws.WebService;



import com.sdo.webservice.entity.Student;



@WebService

public interface StudentWebService {

	 Student getStudentById(int id);

}







这是webservice实现类

[code=java]



package com.sdo.webservice.webservice.impl;



import javax.annotation.Resource;

import javax.jws.WebService;



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

import org.springframework.stereotype.Service;



import com.sdo.webservice.dao.StudentDao;

import com.sdo.webservice.entity.Student;

import com.sdo.webservice.webservice.StudentWebService;





@WebService(endpointInterface = "com.sdo.webservice.webservice.StudentWebService",serviceName="Student")  

@Service

public class StudentWebServiceImpl implements StudentWebService{

    

	@Resource

	private StudentDao studentDao;

	

	@Override

	public Student getStudentById(int id) {

		return studentDao.getStudentById(id);

	}



}

这是mybatis的dao



package com.sdo.webservice.dao;



import com.sdo.webservice.entity.Student;



public interface StudentDao {

   Student getStudentById(int id);

}

这是发布webservice的xml





<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

	xmlns:aop="http://www.springframework.org/schema/aop"

	<jaxws:endpoint id="Student" address="/StudentWebService"

		implementor="com.sdo.webservice.webservice.impl.StudentWebServiceImpl" />



</beans>

这是数据源及其他bean的spring.xml

这里写个客户端

import org.apache.cxf.jaxws.JaxWsProxyFactoryBean;



import com.sdo.webservice.entity.Student;

import com.sdo.webservice.webservice.StudentWebService;



public class Client {  

    public static void main(String[] args) {  

        JaxWsProxyFactoryBean bean = new JaxWsProxyFactoryBean();  

        bean.setServiceClass(StudentWebService.class);  

        bean.setAddress("http://localhost:8080/CXF0621/StudentWebService");  

        StudentWebService studentWebService = (StudentWebService)bean.create();  

        Student student = studentWebService.getStudentById(1);  

        System.out.println(student.toString());  

    } 

}

这是查询的结果
