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

    </aop:config>
