一, 通过IDE创建项目, 并创建相应的包结构

查看web.xml中的StrutsPrepareAndExecuteFilter包名是否正确.不正确的话去掉.ng包.

打开Project Structure and Fix the Problems

二整合Hibernate到Spring中

右键数据库, 创建表

如果遇到如下问题:

解决方法:

手动创建一个sessionFactory

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
    </bean>
</beans>

此时选项中便有了可选项

自动生成如下内容

导入需要的jdbc驱动包后修改配置如下:

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="annotatedClasses">
            <list>
                <value>com.minicuper.ssh.entity.UserEntity</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.connection.url">jdbc:mysql://localhost:3306/ssh</prop>
                <prop key="hibernate.connection.driver_class">com.mysql.jdbc.Driver</prop>
                <prop key="connection.username">root</prop>
                <prop key="connection.password">1234</prop>
                <prop key="current_session_context_class">thread</prop>
                <prop key="format_sql">true</prop>
                <prop key="show_sql">true</prop>
                <prop key="dialect">org.hibernate.dialect.MySQL5Dialect</prop>
                <prop key="hbm2ddl.auto">create</prop>
            </props>
        </property>
    </bean>
</beans>

生成的实体类中有一些错误

解决方法:为sessionFactory指定对应的DataSources即可

三整合Struts到Spring中.

配置ContextLoaderListener, 使WebApp启动时便初始化Spring配置文件
ContextLoaderListener类在spring-web.jar包中.需要手动引入jar包.

web.xml

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee"
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_4_0.xsd"
         version="4.0">
    <filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

    <!--Spring整合-->
    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
    <context-param>
        <param-name>contextConfigLocation</param-name>
        <param-value>classpath:spring-config.xml</param-value>
    </context-param>
</web-app>

创建的类,及修改的类 :

image.png

UserAction.java

package com.minicuper.ssh2.action;
import com.minicuper.ssh2.entity.User;
import com.minicuper.ssh2.service.UserService;
import com.opensymphony.xwork2.ActionSupport;
import com.opensymphony.xwork2.ModelDriven;

public class UserAction extends ActionSupport implements ModelDriven<User> {
    public String result = "";

    private User user = new User();
    @Override
    public User getModel() {
        return user;
    }

    private UserService userService;

    public void setUserService(UserService userService) {
        this.userService = userService;
    }

    public String regist(){
        System.out.println("UserAction regist()");
        if(userService.regist(user)){
            result = "注册成功";
            return SUCCESS;
        }else {
            result = "注册失败";
            return ERROR;
        }
    }
}

User.java

package com.minicuper.ssh2.entity;

import javax.persistence.Basic;
import javax.persistence.Column;
import javax.persistence.Entity;
import javax.persistence.Id;
import java.util.Objects;

@Entity
public class User {
    private int uid;
    private String name;
    private String pwd;

    @Id
    @Column(name = "uid")
    public int getUid() {
        return uid;
    }

    public void setUid(int uid) {
        this.uid = uid;
    }

    @Basic
    @Column(name = "name")
    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Basic
    @Column(name = "pwd")
    public String getPwd() {
        return pwd;
    }

    public void setPwd(String pwd) {
        this.pwd = pwd;
    }

    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (o == null || getClass() != o.getClass()) return false;
        User user = (User) o;
        return uid == user.uid &&
                Objects.equals(name, user.name) &&
                Objects.equals(pwd, user.pwd);
    }
    @Override
    public int hashCode() {
        return Objects.hash(uid, name, pwd);
    }
}

UserService.java

package com.minicuper.ssh2.service;

import com.minicuper.ssh2.dao.UserDao;
import com.minicuper.ssh2.entity.User;

public class UserService {
    private UserDao userDao;

    public void setUserDao(UserDao userDao) {
        this.userDao = userDao;
    }

    public boolean regist(User user){
        System.out.println("UserService regist()");
        return userDao.regist(user);
    }
}

UserDao.java

package com.minicuper.ssh2.dao;

import com.minicuper.ssh2.entity.User;
import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.Transaction;
import org.springframework.transaction.annotation.Transactional;

public class UserDao {
    private SessionFactory sessionFactory;

    public void setSessionFactory(SessionFactory sessionFactory) {
        this.sessionFactory = sessionFactory;
    }

    public boolean regist(User user){
        System.out.println("UserDao regist()");
        Session currentSession = sessionFactory.openSession();
        Transaction transaction = currentSession.beginTransaction();
        try {
            currentSession.save(user);
            transaction.commit();
            return true;
        }catch (Exception e){
            e.printStackTrace();
            transaction.rollback();
        }finally {
            currentSession.close();
            sessionFactory.close();
        }
        return false;
    }
}

常见问题:

sessionFactory.getCurrentSession()
异常: org.hibernate.HibernateException: Could not obtain transaction-synchronized Session for current thread
配置不起作用:<prop key="current_session_context_class">thread</prop>
解决方法: 配置HibernateTransactionManager
在Spring配置文件中添加:

    <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>

    <tx:annotation-driven/>

后在Service类上添加注解:@Transactional

配置事务时
出现异常:org.hibernate.service.UnknownUnwrapTypeException: Cannot unwrap to requested type [javax.sql.DataSource]
解决方法:
1.导入c3p0相关的包.
2.修改spring.config.xml
3.Dao类中原来的事务操作删掉即可

    添加
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="com.mysql.cj.jdbc.Driver"/>
        <property name="user" value="root"/>
        <property name="password" value="1234"/>
        <property name="jdbcUrl" value="jdbc:mysql://localhost:3306/ssh?serverTimezone=UTC"/>
    </bean>
    修改
    <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <property name="annotatedClasses">
            <list>
                <value>com.minicuper.practice.entity.User</value>
            </list>
        </property>
        <property name="hibernateProperties">
            <props>
                <prop key="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</prop>
                <prop key="show_sql">true</prop>
                <prop key="format_sql">true</prop>
                <prop key="hbm2ddl.auto">create</prop>
            </props>
        </property>
    </bean>
    添加
    <bean id="transactionManager" class="org.springframework.orm.hibernate5.HibernateTransactionManager">
        <property name="sessionFactory" ref="sessionFactory"/>
    </bean>
    添加
    <tx:annotation-driven/>

配置c3p0时: 出现 ClassNotFoundException: com.mchange.v2.ser.Indirector
解决方法:添加 mchange-commons-java.jar包
