mybatis+spring3+mysql整合的webservice

  接触mybatis有段时间了，mybatis是ibatis的升级版，两者还是有些差别的，最明显的是映射的 SQL 语句与接口中的方法绑定。

今天来整合一下RT的webservice，利用xml写一个对应的包含Mapper信息的配置文件来实现。看截图里的各个package结构，先把package建立起来。



那么，整合首先从spring的applicationContext-common.xml文件开始。

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

然后一个个配置文件来web.xml

这里呢，我们首先在mysql数据库建立一个Person的table

然后在model package里建立po  Person.java

package com.cenyi.model;

/**
*
* @项目名称：mybatisWebservice
* @类名称：Person
* @类描述：
* @创建人：cenyi
* @创建时间：2015-3-21 下午10:50:38
* @version： 1.0
*
*/
public class Person {

private String id;
private String name;
private int age;
private String birthday;
private double hight;
public String getId() {
return id;
}
public void setId(String id) {
this.id = id;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public int getAge() {
return age;
}
public void setAge(int age) {
this.age = age;
}
public String getBirthday() {
return birthday;
}
public void setBirthday(String birthday) {
this.birthday = birthday;
}
public double getHight() {
return hight;
}
public void setHight(double hight) {
this.hight = hight;
}

}

然后来我们的Dao接口PersonDao.java

package com.cenyi.dao;

import java.util.List;

import com.cenyi.model.Person;

/**
*
* @项目名称：mybatisWebservice
* @类名称：PersonDao
* @类描述：
* @创建人：cenyi
* @创建时间：2015-3-21 下午10:02:14
* @version： 1.0
*
*/

public interface PersonDao {

public void insertPerson(Person person);
public void updatePerson(Person person);
public List<Person> findPerson(String name);
public void deletePerson(String id);
}

并且建立接口的实现类PersonDaoImpl.java

package com.cenyi.dao.impl;

import java.util.List;

import javax.annotation.Resource;

import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.support.SqlSessionDaoSupport;

import com.cenyi.dao.PersonDao;
import com.cenyi.model.Person;

/**
*
* @项目名称：mybatisWebservice
* @类名称：PersonDaoImpl
* @类描述：
* @创建人：cenyi
* @创建时间：2015-3-22 上午12:04:10
* @version： 1.0
*
*/
public class PersonDaoImpl extends SqlSessionDaoSupport implements PersonDao {

private SqlSessionTemplate sqlSessionTemplate;

public SqlSessionTemplate getSqlSessionTemplate() {
return sqlSessionTemplate;
}

@Resource(name="sqlSessionTemplate")
public void setSqlSessionTemplate(SqlSessionTemplate sqlSessionTemplate) {
this.sqlSessionTemplate = sqlSessionTemplate;
}

public void deletePerson(String id) {
getSqlSession().delete("com.cenyi.dao.PersonDao.deletePerson", id);
}

public List<Person> findPerson(String name) {
return getSqlSession().selectList("com.cenyi.dao.PersonDao.findPerson", name);
}

public void insertPerson(Person person) {
getSqlSession().insert("com.cenyi.dao.PersonDao.insertPerson", person);
}

public void updatePerson(Person person) {
getSqlSession().update("com.cenyi.dao.PersonDao.updatePerson", person);
}

}

然后我们要写一个包含mapper信息的xml了PersonMapper.xml（如之前提到的，还可以用另外一种定义一个Mapper接口、通过注解辅助的方式来实现）

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd">

<mapper namespace="com.cenyi.dao.PersonDao">

<insert id="insertPerson" parameterType="Person" useGeneratedKeys="true" keyColumn="id">
insert into Person(id, name, age, birthday, hight, time) values(#{id}, #{name}, #{age}, #{birthday}, #{hight}, now())
</insert>

<update id="updatePerson" parameterType="Person">
update Person
<set>
<if test="name != null">name=#{name},</if>
<if test="age != null">age=#{age},</if>
<if test="birthday != null">birthday=#{birthday},</if>
<if test="hight != null">hight=#{hight}</if>
</set>
where id=#{id}
</update>

<resultMap type="Person" id="personMap">
<result column="id" property="id" />
<result column="name" property="name" />
<result column="age" property="age" />
<result column="birthday" property="birthday" />
<result column="hight" property="hight" />
</resultMap>

<select id="findPerson" parameterType="Person" resultType="list" resultMap="personMap">
select * from Person where 1=1 and name=#{name}
</select>

<delete id="deletePerson" parameterType="string">
delete from Person where id=#{id}
</delete>
</mapper>

紧接着，来写service层PersonService.java。

package com.cenyi.service;

import java.util.List;

import com.cenyi.model.Person;

/**
*
* @项目名称：mybatisWebservice
* @类名称：PersonService
* @类描述：
* @创建人：cenyi
* @创建时间：2015-3-21 下午11:42:04
* @version： 1.0
*
*/
public interface PersonService {

public void insertPerson(Person person);
public void updatePerson(Person person);
public List<Person> findPerson(String name);
public void deletePerson(String id);
}

和其实现类PersonServiceImpl.java

package com.cenyi.service.impl;

import java.util.List;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.cenyi.dao.PersonDao;
import com.cenyi.model.Person;
import com.cenyi.service.PersonService;

/**
*
* @项目名称：mybatisWebservice
* @类名称：PersonServiceImpl
* @类描述：
* @创建人：cenyi
* @创建时间：2015-3-21 下午11:42:37
* @version： 1.0
*
*/

@Service
@Transactional
public class PersonServiceImpl implements PersonService {

@Resource
private PersonDao personDao;

public PersonDao getPersonDao() {
return personDao;
}
public void setPersonDao(PersonDao personDao) {
this.personDao = personDao;
}

public void deletePerson(String id) {
personDao.deletePerson(id);
}

public List<Person> findPerson(String name) {
return personDao.findPerson(name);
}

public void insertPerson(Person person) {
personDao.insertPerson(person);
}

public void updatePerson(Person person) {
personDao.updatePerson(person);
}

}

最后呢，来写webservice的接口了，

package com.webservice;

import com.cenyi.model.Person;

/**
*
* @项目名称：mybatisWebservice
* @类名称：myWebservice
* @类描述：
* @创建人：cenyi
* @创建时间：2015-3-22 上午08:40:22
* @version： 1.0
*
*/

public interface MyWebservice {
public String pushData(Person person);
}

这里我使用了线程来操作的，算是对线程的一个练习吧。

package com.webservice.impl;

import javax.annotation.Resource;
import javax.jws.WebService;

import org.springframework.stereotype.Component;

import com.cenyi.model.Person;
import com.cenyi.service.PersonService;
import com.webservice.MyWebservice;

/**
*
* @项目名称：mybatisWebservice
* @类名称：MyWebserviceImpl
* @类描述：
* @创建人：cenyi
* @创建时间：2015-3-22 上午09:10:41
* @version： 1.0
*
*/

@WebService(targetNamespace="impl.webservice.com", portName="MyWebserviceImplPort", serviceName="MyWebserviceImplSerivce")
@Component
public class MyWebserviceImpl implements MyWebservice {

@Resource
private PersonService personService;

public String pushData(Person person) {
StringBuffer sb = new StringBuffer("");
CrudThread ct = new CrudThread(personService, sb, person);
Thread t = new Thread(ct);
t.start();
System.err.println(sb.toString());
return sb.toString();
}

}

class CrudThread implements Runnable{

private PersonService personService;
public StringBuffer sb;
public Person person;

public CrudThread(PersonService personService, StringBuffer sb, Person person) {
this.personService = personService;
this.sb =sb;
this.person = person;
}

public void run() {
try {
sb.append("进入了webservice了...\r");
Thread.sleep(3000);
//insert
sb.append("开始添加信息");
Thread.sleep(3000);
//		Person person = new Person();
//		person.setAge(30);
//		person.setBirthday("1990-1-1");
//		person.setHight(175.12D);
//		person.setName("cenyi");
personService.insertPerson(person);
sb.append("完成添加信息\r");
Thread.sleep(3000);
//query
Person p = personService.findPerson("cenyi").get(0);
System.out.println("insert完成："+p.getId()+", "+p.getName()+", "+p.getAge()+", "+p.getHight()+", "+p.getBirthday().toString());
//update
sb.append("开始修改信息\r");
Thread.sleep(3000);
p.setAge(26);
p.setName("Tom");
p.setHight(172D);
personService.updatePerson(p);
sb.append("完成修改信息\r");
Thread.sleep(3000);
//query
Person per = personService.findPerson(p.getName()).get(0);
System.out.println("update完成："+per.getId()+", "+per.getName()+", "+per.getAge()+", "+per.getHight()+", "+per.getBirthday().toString());
//delete
//			sb.append("开始删除信息\r");
//			personService.deletePerson(p.getId());
//			sb.append("完成删除信息\r");
//			Thread.sleep(3000);
//			//insert
//			sb.append("再次insert信息\r");
//			personService.insertPerson(person);
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

最后我们需要建一个client来验证这个webservice了。生成客户的方法呢，可以直接在myeclipse上实现，具体的方法请大家查看我的博文里有篇详细的spring+ibatis+mysql整合的webservice，里边有详细的截图来告知大家如何生成webservice的client。最终测试ok的。
