SSH_框架整合1

1　WEB环境下配置Spring

　   因为是在WEB环境中应用Spring,所以要先配置web.xml:

(1)WebContent-WEB-INF-lib包中，加入Spring包下的required的所有jar包；

　 (2)WebContent-WEB-INF下新建web.xml,配置web.xml

 <?xml version="1.0" encoding="UTF-8"?>
 <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">

     <!-- 配置spring配置文件.xml的名称和位置路径 -->
     <context-param>
         <param-name>contextConfigLocation</param-name>
         <param-value>classpath:applicationContext*.xml</param-value>
     </context-param>

     <!-- Bootstraps the root web application context before servlet initialization -->
     <listener>
         <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
     </listener>

 </web-app>

(3)src下新建Source-folder包：conf，新建applicationContext.xml（暂时不需要写）

2 加入Hibernate

　　(1)建立持久化类，生成对应的 .hbm.xml 文件, 生成对应的数据表；

　　(2)Spring整合Hibernate

　　(3) 步骤：

　　　　①加入Hibernate的jar包，加入MySQL和c3p0驱动；

　　　　②conf报下配置hibernate.cfg.xml文件

　　

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE hibernate-configuration PUBLIC
         "-//Hibernate/Hibernate Configuration DTD 3.0//EN"
         "http://hibernate.sourceforge.net/hibernate-configuration-3.0.dtd">
 <hibernate-configuration>
     <session-factory>

         <property name="hibernate.dialect">org.hibernate.dialect.MySQL5InnoDBDialect</property>
         <property name="hibernate.show_sql">true</property>
         <property name="hibernate.format_sql">true</property>
         <property name="hibernate.hbm2ddl.auto">update</property>
     </session-factory>
 </hibernate-configuration>

　　　　③src下新建实体类：com.atguigu.ssh.entities：Department.java和Employee.java　　

Department.java：

　　

 package com.atguigu.ssh.entities;

 public class Department {

     private Integer id;
     private String departmentName="";
     public Integer getId() {
         return id;
     }
     public void setId(Integer id) {
         this.id = id;
     }
     public String getDepartmentName() {
         return departmentName;
     }
     public void setDepartmentName(String departmentName) {
         this.departmentName = departmentName;
     }

 }

Employee.java：

　　

 package com.atguigu.ssh.entities;

 import java.util.Date;

 public class Employee {
     private Integer id;

     private String lastName="";
     private String email;

     private Date birth;
     private Date createTime;

     private Department department;

     public Integer getId() {
         return id;
     }

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

     public String getLastName() {
         return lastName;
     }

     public void setLastName(String lastName) {
         this.lastName = lastName;
     }

     public String getEmail() {
         return email;
     }

     public void setEmail(String email) {
         this.email = email;
     }

     public Date getBirth() {
         return birth;
     }

     public void setBirth(Date birth) {
         this.birth = birth;
     }

     public Date getCreateTime() {
         return createTime;
     }

     public void setCreateTime(Date createTime) {
         this.createTime = createTime;
     }

     public Department getDepartment() {
         return department;
     }

     public void setDepartment(Department department) {
         this.department = department;
     }

 }

　　 　　④生成对应的.hbm.xml持久化类映射文件：Department.hbm.xml，Employee.hbm.xml

　　　　⑤conf包下新建db.properties文件：　

　　

 jdbc.user=root
 jdbc.password=920614
 jdbc.driverClass=com.mysql.jdbc.Driver
 jdbc.jdbcUrl=jdbc:mysql:///spring_ssh

 jdbc.initPoolSize=5
 jdbc.maxPoolSize=10
 #...

　　　　⑥再次配置Spring配置文件：applicationContext.xml

         <property name="sessionFactory" ref="sessionFactory"></property>

     <!--2 配置事务属性  -->
     <tx:advice id="txAdvice" transaction-manager="transactionManager">
         <tx:attributes>
             <tx:method name="get*" read-only="true"/>
             <tx:method name="*"/>

         <aop:pointcut expression="execution(* com.atguigu.ssh.service.*.*(..))" id="txPointCut"/>
         <aop:advisor advice-ref="txAdvice" pointcut-ref="txPointCut"/>
     </aop:config>

 </beans>
