struts-2.3.20
spring-4.1.4
hibernate-4.3.8
slf4j-1.7.10
mysql> create database myoa default character set utf8
2.在MyEclipse中建立Web Project
在项目上右键-Properties,设置编码为UTF-8.
3.配置Struts2
<constant name="struts.devMode" value="true" /><constant name="struts.action.extension" value="action" /><constant name="struts.ui.theme" value="simple"/>
4.配置Hibernate
<session-factory name="foo"><property name="dialect">org.hibernate.dialect.MySQLDialect</property><property name="connection.url">jdbc:mysql:///myoa</property><property name="connection.username">root</property><property name="connection.passWord">123456</property><property name="connection.driver_class">com.mysql.jdbc.Driver</property><property name="show_sql">true</property><property name="hbm2ddl.auto">update</property><mapping resource="User.hbm.xml" /></session-factory>
5.配置Spring
<context:component-scan base-package="com.yangleda.oa"/>
6.整合Spring与Struts2
<listener><listener-class>org.springframework.web.context.ContextLoaderListener</listener-class></listener><context-param><param-name>contextConfigLocation</param-name><param-value>classpath:applicationContext*.xml</param-value></context-param>
测试:
@Controller@Scope("prototype")public class TestAction extends ActionSupport {private static final long serialVersionUID = 1L;@Overridepublic String execute() throws Exception {return SUCCESS;}}
<action name="test" class="testAction"><result>/WEB-INF/SSH.jsp</result></action>
7.整合Spring与Hibernate
jdbcUrl=jdbc:mysql:///myoadriverClass=com.mysql.jdbc.Driveruser=rootpassword=123456
<!-- 导入外部的properties文件 --><context:property-placeholder location="classpath:jdbc.properties"/><!-- 配置SessionFactory --><bean id="sessionFactory" class="org.springframework.orm.hibernate3.LocalSessionFactoryBean"><!-- 指定hibernate的配置文件位置 --><property name="configLocation" value="classpath:hibernate.cfg.xml"></property><!-- 配置c3p0数据库连接池 --><property name="dataSource"><bean class="com.mchange.v2.c3p0.ComboPooledDataSource"><!-- 数据连接信息 --><property name="jdbcUrl" value="${jdbcUrl}"></property><property name="driverClass" value="${driverClass}"></property><property name="user" value="${user}"></property><property name="password" value="${password}"></property><!-- 其他配置 --><!--初始化时获取三个连接,取值应在minPoolSize与maxPoolSize之间。Default: 3 --><property name="initialPoolSize" value="3"></property><!--连接池中保留的最小连接数。Default: 3 --><property name="minPoolSize" value="3"></property><!--连接池中保留的最大连接数。Default: 15 --><property name="maxPoolSize" value="5"></property><!--当连接池中的连接耗尽的时候c3p0一次同时获取的连接数。Default: 3 --><property name="acquireIncrement" value="3"></property><!-- 控制数据源内加载的PreparedStatements数量。如果maxStatements与maxStatementsPerConnection均为0,则缓存被关闭。Default: 0 --><property name="maxStatements" value="8"></property><!--maxStatementsPerConnection定义了连接池内单个连接所拥有的最大缓存statements数。Default: 0 --><property name="maxStatementsPerConnection" value="5"></property><!--最大空闲时间,1800秒内未使用则连接被丢弃。若为0则永不丢弃。Default: 0 --><property name="maxIdleTime" value="1800"></property></bean></property></bean><!-- 配置声明式事务管理(采用注解的方式) --><bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager"><property name="sessionFactory" ref="sessionFactory"></property></bean><tx:annotation-driven transaction-manager="txManager"/>
以上<beans>中要加入“xmlns:tx="http://www.springframework.org/schema/tx"”的命名申明,并在“xsi:schemaLocation”中指定schema的地址“http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd”.
测试:
public class User {private int id;private String name;public int getId() {return id;}public void setId(int id) {this.id = id;}public String getName() {return name;}public void setName(String name) {this.name = name;}}
<class name="User" table="test_user"><id name="id"><generator class="native" /></id></class>
@Servicepublic class TestService {@Resourceprivate SessionFactory sessionFactory;@Transactionalpublic void saveTwo() {Session session = sessionFactory.getCurrentSession();session.save(new User());// int a = 1 / 0;session.save(new User());}}
@Resourceprivate TestService testService;@Overridepublic String execute() throws Exception {testService.saveTwo();return SUCCESS;}
8.整理资源文件夹Source Folder:src,config,test.Folder:Web Root/script,Web Root/style,Web Root/WEB-INF/jsp.
9.配置slf4j
log4j.rootLogger=warn, stdoutlog4j.logger.com.yangleda.oa=debug
