SSH Struts2+hiberante+Spring整合

使用SSH框架编写学生信息:

一.新建Java工程:

(1)建立好Java各层级之间的结构:业务处理层dao,数据模型层domain,页面请求处理层(Struts2 MVC层)action,service层.

(2)建立好各层的实现类及接口;

(3)建立一个source folder文件夹,用来存放一些配置问价.

(4)改变字节码生成的位置,改为WEB-INF下面的classes文件夹下.

Java工程层级结构如下图:

二.hibernate整合到Spring容器中

步骤:

1.编写domain,数据模型,此例子为Student类.

package com.xk.ssh.proj.domian;

public class Student {
    private Integer id;
    private String name;
    private Integer age;
    private double fees;
    private long contact;
    public Student() {
    }
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
    public double getFees() {
        return fees;
    }
    public void setFees(double fees) {
        this.fees = fees;
    }
    public long getContact() {
        return contact;
    }
    public void setContact(long contact) {
        this.contact = contact;
    }
    @Override
    public String toString() {
        return "Student [id=" + id + ", name=" + name + ", age=" + age + ", fees=" + fees + ", contact=" + contact
                + "]";
    }
    public Student(Integer id, String name, Integer age, double fees, long contact) {
        this.id = id;
        this.name = name;
        this.age = age;
        this.fees = fees;
        this.contact = contact;
    }
    public Student( String name, Integer age, double fees, long contact) {
        this.name = name;
        this.age = age;
        this.fees = fees;
        this.contact = contact;
    }
    public Student(Integer id) {
        this.id = id;
    }
}

2.遍写映射文件,在domain文件夹下编写Student.xml文件.hibernate主要用来管理数据库.

<?xml version="1.0"?>
<!DOCTYPE hibernate-mapping PUBLIC
    "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
    "http://www.hibernate.org/dtd/hibernate-mapping-3.0.dtd">
<hibernate-mapping package="com.xk.ssh.proj.domian">
    <class name="Student" table="Student">
        <id name="id" column="s_id">
            <generator class="native" />
        </id>
        <property name="name" column="s_name" />
        <property name="age" column="s_age" />
        <property name="fees" column="s_fees" />
        <property name="contact" column="s_phone" />
    </class>
</hibernate-mapping>

3.编写Dao接口及Dao的实现类

package com.xk.ssh.proj.dao;
import java.util.List;
import com.xk.ssh.proj.domian.Student;
public interface IStudentDao {
    public void save(Student stu);
    public void delete(Student stu);
    public void update(Student stu);
    public Student get(Student stu);
    public List<Student> list();
}

package com.xk.ssh.proj.dao.impl;

import java.util.List;

import org.hibernate.Session;
import org.hibernate.SessionFactory;


import com.xk.ssh.proj.dao.IStudentDao;
import com.xk.ssh.proj.domian.Student;

public class StudentDaoImpl implements IStudentDao {
    // 在Dao中注入SessionFaction
    private SessionFactory sessionfactory;
    public void setSessionfactory(SessionFactory sessionfactory) {
        this.sessionfactory = sessionfactory;
    }
    @Override
    public void save(Student stu) {
        Session session = sessionfactory.getCurrentSession();
        session.save(stu);
    }
    @Override
    public void delete(Student stu) {
        Session session = sessionfactory.getCurrentSession();
        session.delete(stu);
    }
    @Override
    public void update(Student stu) {
        Session session = sessionfactory.getCurrentSession();
        session.update(stu);
    }
    @Override
    public Student get(Student stu) {
        Session session = sessionfactory.getCurrentSession();
        // Student.class:Student的字节码文件
        return (Student) session.get(Student.class, stu.getId());
    }
    @SuppressWarnings("unchecked")
    @Override
    public List<Student> list() {
        // 查询session.createQuery("sql语句").list
        Session session = sessionfactory.getCurrentSession();
        return session.createQuery("SELECT stu FROM Student stu").list();
    }
}

4.拷贝架包:数据驱动的hibernate包,Spring的core,test,bean,context等

antlr-2.7.7.jar
asm-3.3.jar
asm-commons-3.3.jar
asm-tree-3.3.jar

5.Spring的配置文件:

　　①添加并配置.properties文件

　　

<context:property-placeholder location="classpath:db.properties" />

　　②配置DataSource,连接数据库

　　

<!-- 配置DataSource -->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"
        destroy-method="close">
        <!-- 连接数据库 -->
        <property name="driverClassName" value="${jdbc.driverClassName}" />
        <property name="url" value="${jdbc.url}" />
        <property name="username" value="${jdbc.username}" />
        <property name="password" value="${jdbc.password}" />
    </bean>

　　④配置SessionFactory:(jdbc/tx/orm架包)

　　　　使用LocalSessionFactoryBean 创建SessionFactory

　　　　配置dataSource和引用

　　　　配置hibernate中的常规配置(方言)

　　　　配置domain的映射文件

　　

    <!-- 配置sessionFactory -->
    <bean id="sessionFactory"
        class="org.springframework.orm.hibernate4.LocalSessionFactoryBean">

        <!-- 配置连接数据库的信息 此处的name是org.springframework.orm.hibernate4.LocalSessionFactoryBean类中的dataSource 
            此处的ref是引用配置DateSource中的id -->
        <property name="dataSource" ref="dataSource" />

        <!-- 配置hibernate常规配置 -->
        <property name="hibernateProperties">
            <!-- dialect方言 -->
            <value>
                hibernate.dialect=org.hibernate.dialect.MySQLDialect
                hibernate.hbm2ddl.auto=none
                hibernate.show_sql=true
            </value>
        </property>

        <!-- 配置映射文件,告诉Spring框架*.hbm.xml在哪 此处的name是org.springframework.orm.hibernate4.LocalSessionFactoryBean类中的mappingDirectoryLocations 
            value是自己的对象xml的包的权限定名称 -->
        <property name="mappingDirectoryLocations" value="classpath:com/xk/ssh/proj/domian" />
    </bean>

6.编写Dao

　　①直接在Dao中注入一个SessionFactory;

private SessionFactory sessionfactory;
    public void setSessionfactory(SessionFactory sessionfactory) {
        this.sessionfactory = sessionfactory;
    }

　　②在Dao中直接使用SessionFactory.getCurrentSession()来得到我们需要的session

　　

Session session = sessionfactory.getCurrentSession();

7.在Spring中配置Dao

　　①抽象一个baseDao;

　　<bean id = "baseDao" abstract = "true" />

　　②Dao继承BaseDao;

　　<bean id="stuDao" parent="baseDao"/>

　　

Dao类extends jdbcDaoSupport implements 接口

　8.编写Service

　　①编写Service接口和实现

　　

package com.xk.ssh.proj.service;
import java.util.List;
import com.xk.ssh.proj.domian.Student;
public interface IStudentService {
public void save(Student stu);
    public void delete(Student stu);
    public void update(Student stu);
    public Student get(Student stu);
    public List<Student> list();
}

package com.xk.ssh.proj.service.impl;
import java.util.List;
import com.xk.ssh.proj.dao.IStudentDao;
import com.xk.ssh.proj.domian.Student;
import com.xk.ssh.proj.service.IStudentService;
public class StudentServiceImpl implements IStudentService {
    private IStudentDao student;
    public void setStudent(IStudentDao student) {
        this.student = student;
    }
    @Override
    public void save(Student stu) {
        student.save(stu);
    }
    @Override
    public void delete(Student stu) {
        student.delete(stu);
    }
    @Override
    public void update(Student stu) {
        student.update(stu);
    }
    @Override
    public Student get(Student stu) {
        return student.get(stu);
    }
    @Override
    public List<Student> list() {
        return student.list();
    }
}

　　②在Spring中配置事物servicebean

　　

<!-- 配置service id为唯一标识,class为service的实现类 name为service实现类中注入的dao层对象 ref为引用Dao -->
    <bean id="stuService" class="com.xk.ssh.proj.service.impl.StudentServiceImpl">
        <property name="student" ref="stuDao" />
    </bean>

　9.配置事物

　　

    <!-- 配置事务管理器 -->
    <bean id="txMgr"
        class="org.springframework.orm.hibernate4.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory" />
    </bean>

    <!-- 配置事物 事物是配置给service实现的 -->
    <aop:config>
        <!-- pointcut:切点 ; Advice:通知 advisor:切点和通知的配置器 下面是配置切点:advice-ref:引用通知的ID -->
        <aop:pointcut expression="execution(* com.xk.ssh.proj.service.*.*(..))"
            id="stuTC" />
        <aop:advisor advice-ref="StuAdvice" pointcut-ref="stuTC" />
    </aop:config>

    <tx:advice id="StuAdvice" transaction-manager="txMgr">
        <tx:attributes>
            <!-- 过滤方法,将所有以get和list开头的方法标记为只读 -->
            <tx:method name="get*" read-only="true" />
            <tx:method name="list*" read-only="true" />
            <tx:method name="*" />
        </tx:attributes>
    </tx:advice>

三.将Struts2 集成在Spring容器

　　1.导架包:(spring-web/Struts-spring-plugin...jar)

　　2.编写Struts.xml(位置与源文件夹同级)

　　

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
    <constant name="struts.action.extension" value="action,nice,,"></constant> <!-- 加后缀 -->
    <constant name="struts.devMode" value="true" />  <!-- 小的改动不需要再启动服务器 -->
    <constant name="struts.enable.DynamicMethodInvocation" value="true"/> <!-- 动态调用 -->
     
     <package name="hello" extends="struts-default">
         <action name="list_*" class="StuAction" method="{1}">
             <result name="list">/WEB-INF/views/SSH.jsp</result>
         </action>
     </package>
</struts>

　　3.编写web.xml文件(位置在WEB-INF文件夹下面)

　　

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">
<struts>
    <constant name="struts.action.extension" value="action,nice,,"></constant> <!-- 加后缀 -->
    <constant name="struts.devMode" value="true" />  <!-- 小的改动不需要再启动服务器 -->
    <constant name="struts.enable.DynamicMethodInvocation" value="true"/> <!-- 动态调用 -->
     
     <package name="hello" extends="struts-default">
         <action name="list_*" class="StuAction" method="{1}">
             <result name="list">/WEB-INF/views/SSH.jsp</result>
         </action>
     </package>
</struts>

　　4.编写Action (页面请求)

　　

package com.xk.ssh.proj.mvc;
import java.util.List;
import com.opensymphony.xwork2.ActionContext;
import com.opensymphony.xwork2.ActionSupport;
import com.xk.ssh.proj.domian.Student;
import com.xk.ssh.proj.service.IStudentService;
public class StudentAction extends ActionSupport {
    private static final long serialVersionUID = 1L;
    private IStudentService studentService;
    public void setStudentService(IStudentService studentService) {
        this.studentService = studentService;
    }
    public String list() {
        List<Student> list = studentService.list();
        ActionContext context = ActionContext.getContext();
        context.put("key", list);
        System.out.println(list);
        return "list";
    }
}

5.在applicationcontext.xml中配置action

　　

<!-- 配置Action -->
    <bean id="StuAction" class="com.xk.ssh.proj.mvc.StudentAction">
        <property name="studentService" ref="stuService"/>
    </bean>

6.编写Struts的配置文件:在action的class属性中填写的是此action在applicationcontext.xml中对应的bean的id

7.在web.xml中添加listener监听器

8.在web.xml中添加Spring框架启动的加载文件配置路径

<context-param > 
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:applicationcontext.xml</param-value>
    </context-param>

四.附上完整代码:

//domain
package com.xk.ssh.proj.domian;

public class Student {
    private Integer id;
    private String name;
    private Integer age;
    private double fees;
    private long contact;
    public Student() {
    }
    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public Integer getAge() {
        return age;
    }
    public void setAge(Integer age) {
        this.age = age;
    }
    public double getFees() {
        return fees;
    }
    public void setFees(double fees) {
        this.fees = fees;
    }
    public long getContact() {
        return contact;
    }
    public void setContact(long contact) {
        this.contact = contact;
    }
    @Override
    public String toString() {
        return "Student [id=" + id + ", name=" + name + ", age=" + age + ", fees=" + fees + ", contact=" + contact
                + "]";
    }
    public Student(Integer id, String name, Integer age, double fees, long contact) {
        this.id = id;
        this.name = name;
        this.age = age;
        this.fees = fees;
        this.contact = contact;
    }
    public Student( String name, Integer age, double fees, long contact) {
        this.name = name;
        this.age = age;
        this.fees = fees;
        this.contact = contact;
    }
    public Student(Integer id) {
        this.id = id;
    }
}
