使用CXF開發WebService程序的總結(七)：Spring+CXF+Mybatis+Mysql共同打造的服務端示例
經過該demo，能夠 熟悉下 spring+cxf+maven+mybatis+mysql等常見後端技術整合html
1. 在前面的 父工程 ws_parent 中 添加依賴
因爲原來的項目是使用的cxf依賴，如今須要集成spring，mybatis，因此須要在父工程添加依賴，最新的父工程的pom文件以下：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

2. 新建一個maven子工程 ws_ssm_server
2.1 新建一個子工程，打包方式爲 war格式，由於spring的不少依賴有重複，經整理後 其pom文件以下：
<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/xsd/maven-4.0.0.xsd">

2.2 spring整合cxf
2.2.1 在web.xml中添加 cxf 攔截器處理器配置,以及 spring容器啓動建立配置
<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5"
xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee

<!-- 字符編碼過濾器，必須放在過濾器的最上面 -->

<url-pattern>/cxf/*</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>
</web-app>
2.2.2 在resource目錄下 建立文件夾 spring，在裏面建立spring與cxf集成的配置文件 ： spring-cxf.xml
這裏注意要添加一個 jaxws的命名空間，以及引入兩個 cxf中的 xml配置
<?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:jaxws="http://cxf.apache.org/jaxws" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://cxf.apache.org/jaxws http://cxf.apache.org/schemas/jaxws.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd"> <import resource="classpath:META-INF/cxf/cxf.xml" /> <import resource="classpath:META-INF/cxf/cxf-servlet.xml" /> <!-- 定義服務提供者 --> <jaxws:endpoint implementor="#userService" address="/UserService" > <!-- 添加入 in 攔截器 --> <jaxws:inInterceptors> <bean class="com.lonely.interceptor.AuthInterceptor"></bean> <bean class="org.apache.cxf.interceptor.LoggingInInterceptor"></bean> </jaxws:inInterceptors> <!-- 添加 出 out 攔截器 --> <jaxws:outInterceptors> <bean class="org.apache.cxf.interceptor.LoggingOutInterceptor"></bean> </jaxws:outInterceptors> </jaxws:endpoint> </beans>2.2.3 jaxws:endpoint 中的 implementor:對應的服務接口的實現類，而 address ：對應發佈的接口路徑，注意在實際的接口實現類上 使用註解 @Component讓spring 掃描發現管理，給個別名用於在了 implementor屬性上
UserService
package com.lonely.service;
import java.util.List;
import java.util.Map;
import javax.jws.WebService;
import javax.xml.bind.annotation.adapters.XmlJavaTypeAdapter;
import com.lonely.adapter.MapConvertAdapter;
import com.lonely.model.Clazz;
import com.lonely.model.User;
@WebService
public interface UserService {
/**
* 根據班級信息返回該班級的學生列表
*
* @param clazz
* @return
*/
List<User> findUsersByClass(Clazz clazz);
/**
* 查看全部班級信息以及班級下的全部學生
*
* @return
*/
@XmlJavaTypeAdapter(value = MapConvertAdapter.class)
Map<String, List<User>> findAll();
}
UserServiceImpl
package com.lonely.service.impl;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import javax.jws.WebService;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import com.lonely.dao.UserDao;
import com.lonely.model.Clazz;
import com.lonely.model.User;
import com.lonely.service.UserService;
@Component("userService")
@WebService
public class UserServiceImpl implements UserService {
@Autowired
private UserDao userDao;
@Override
public List<User> findUsersByClass(Clazz clazz) {
return this.userDao.findUsersByClass(clazz);
}
@Override
public Map<String, List<User>> findAll() {
List<Clazz> clazzList = this.userDao.findAll();
if (clazzList != null && clazzList.size() != 0) {
Map<String, List<User>> map = new HashMap<>();
for (Clazz clazz : clazzList) {
map.put(clazz.getClassName(), clazz.getUsers());
}
return map;
}
return null;
}
}
2.3 spring整合mybatis
2.3.1 在spring目錄下，添加 spring與mybatis集成的配置 ： spring-datasource.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:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd">
<!-- 配置數據源 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource">
<property name="username" value="${jdbc.jdbcUsername}"></property>
<property name="password" value="${jdbc.jdbcPassword}"></property>
<property name="url" value="${jdbc.jdbcUrl}"></property>
<property name="driverClassName" value="${jdbc.driverClassName}"></property>
</bean>
<!-- 配置sqlsessionfactory -->
<bean id="sqlSessionFactoryBean" class="org.mybatis.spring.SqlSessionFactoryBean">
<!-- 配置數據源 -->
<property name="dataSource" ref="dataSource"></property>
<!-- 配置mybatis配置 -->
<property name="configuration">
<bean class="org.apache.ibatis.session.Configuration">
<!-- 開啓駝峯命名法 -->
<property name="mapUnderscoreToCamelCase" value="true"></property>
<!-- 當檢測出未知列（或未知屬性）時，如何處理，默認狀況下沒有任何提示，這在測試的時候很不方便，不容易找到錯誤。
可選值：
NONE : 不作任何處理 (默認值)
WARNING : 警告日誌形式的詳細信息
FAILING : 映射失敗，拋出異常和詳細信息
-->
<property name="autoMappingUnknownColumnBehavior" value="WARNING"></property>
</bean>
</property>
<!-- 配置mapping掃描 -->
<property name="mapperLocations" value="classpath:mapper/**/*.xml"></property>
<!-- 配置別名包掃描 -->
<property name="typeAliasesPackage" value="com.lonely.model"></property>
<!-- 配置pagehelper 數據庫方言 -->
<property name="plugins">
<list>
<bean class="com.github.pagehelper.PageHelper">
<property name="properties">
<value>dialect=mysql</value>
</property>
</bean>
</list>
</property>
</bean>
<!-- 配置 接口與 mapper的映射 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.lonely.dao"></property>
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactoryBean"></property>
</bean>
<!-- 配置事務 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!-- 開啓事務註解 -->
<tx:annotation-driven transaction-manager="transactionManager"/>
</beans>
2.3.2 在 basePackage 對應的路徑下 編寫 dao層的接口
package com.lonely.dao;
import java.util.List;
import com.lonely.model.Clazz;
import com.lonely.model.User;
public interface UserDao {
List<User> findUsersByClass(Clazz clazz);
List<Clazz> findAll();
}
2.3.3 在 mapperLocations 對應的路徑下 編寫 mybatis的sql操做的xml文件，這裏好比以下:
<?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.lonely.dao.UserDao">
<resultMap type="clazz" id="clazzMap">
<id property="classId" column="classId"/>
<result property="className" column="className"/>
<collection property="users" ofType="user">
<id column="id" property="id"/>
<result property="userName" column="userName"/>
<result property="classId" column="classId"/>
</collection>
</resultMap>
<!-- 根據班級信息查詢全部學生 -->
<select id="findUsersByClass" parameterType="clazz" resultType="user">
SELECT * from user u where u.classId = #{classId}
</select>
<!-- 查詢全部班級信息以及班級下的全部學生列表 -->
<select id="findAll" resultMap="clazzMap">
SELECT
*
FROM
clazz c
JOIN USER u ON c.classId = u.classId
</select>
</mapper>
2.3.4 在這裏 使用了 mybatis的一對多，因此在 Clazz實體類上 多加了一個屬性 List<User> users;
2.3.5 忘了 前面還須要一個 jdbc.properties
## jdbc環境配置 jdbc.driverClassName = com.mysql.jdbc.Driver jdbc.jdbcUrl = jdbc:mysql://localhost:3306/test?characterEncoding=UTF-8&allowMultiQueries=true jdbc.jdbcUsername = root jdbc.jdbcPassword = xxx #jdbc.logAbandoned = false #jdbc.initialSize = 20 #jdbc.maxActive =1000 #jdbc.maxIdle=100 #jdbc.maxWait = 1000 #jdbc.minEvictableIdleTimeMillis = 300000 #jdbc.minIdle = 10 #jdbc.removeAbandoned = true #jdbc.removeAbandonedTimeout = 3000 #jdbc.timeBetweenEvictionRunsMillis = 10000 #jdbc.testOnBorrow = false #jdbc.testWhileIdle = true #jdbc.validSql = select now()
2.4 spring+cxf+mybatis
2.4.1 在spring目錄下 建立一個spring的核心文件 application.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:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd"> <!-- 引入配置文件 --> <context:property-placeholder file-encoding="UTF-8" location="classpath:properties/jdbc.properties"/> <!-- 包掃描 --> <context:component-scan base-package="com.lonely"></context:component-scan> <!-- spring與mybaties的整合 --> <import resource="spring-datasource.xml"/> <!-- spring與cxf的整合 --> <import resource="spring-cxf.xml"/> </beans>2.4.2 至此，spring+cxf+mybatis整合完畢，整個項目結構以下
3. 使用wsdl2java工具生成客戶端代碼，跟原來的ws_client相似，直接測試便可
