  • ssh整合思想 Spring与Hibernate和Struts2的action整合 调用action添加数据库 使用HibernateTemplate的save(entity)方法 ognl.MethodFailedException:Method"execute" failed for ssh包合集下载

    自动调用Spring的bean.xml配置文件

    需要web.xml启动文件

    代码如下:

    <?xml version="1.0" encoding="UTF-8"?>
    <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">
      <display-name>2018-01-03_Spring_Hibernate</display-name>
      
      <context-param>
      <param-name>contextConfigLocation</param-name>
      <param-value>classpath:bean.xml</param-value>
      </context-param>
      
      <listener>
      <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
      </listener>
      
      <filter>
      <filter-name>struts2</filter-name>
      <filter-class> org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
      </filter>
      <filter-mapping>
      <filter-name>struts2</filter-name>
      <url-pattern>/*</url-pattern>
      </filter-mapping>
      
      <welcome-file-list>
        <welcome-file>index.html</welcome-file>
        <welcome-file>index.htm</welcome-file>
        <welcome-file>index.jsp</welcome-file>
        <welcome-file>default.html</welcome-file>
        <welcome-file>default.htm</welcome-file>
        <welcome-file>default.jsp</welcome-file>
      </welcome-file-list>
    </web-app>

    其中调用了过滤器和监听器

    Spring核心配置文件bean.xml代码

    <?xml version="1.0" encoding="UTF-8"?>
    <beans xmlns="http://www.springframework.org/schema/beans"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"

            http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    
        <!-- c3p0连接池得到dataSource -->
        <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
            <property name="driverClass" value="com.mysql.jdbc.Driver"></property>

        </bean>
        
        <bean id="userAction" class="com.swift.action.UserAction" scope="prototype">
        <property name="userService" ref="userService"></property>
        </bean>
    
        <bean id="sessionFactory" class="org.springframework.orm.hibernate5.LocalSessionFactoryBean">
        <!-- Hibernate核心配置文件没有连接数据库,所以需要注入 -->
        <property name="dataSource" ref="dataSource"></property>
        <!-- Hibernate核心配置文件的位置 -->
        <property name="configLocations" value="classpath:hibernate.cfg.xml"></property>
        </bean>
        
        <bean id="userService" class="com.swift.service.UserService">

        </bean>
        
        <bean id="userDaoImplements" class="com.swift.dao.UserDaoImplements">
        <property name="hibernateTemplate" ref="hibernateTemplate"></property>
        </bean>
        
        <bean id="hibernateTemplate" class="org.springframework.orm.hibernate5.HibernateTemplate">
           <!-- 前一个sessionFactory是HibernateTemplate类内部的 -->
        <property name="sessionFactory" ref="sessionFactory"></property>
        </bean>
        
    
    </beans>

    配置文件注入对象属性,注意需要类当中声明属性并设置setter方法

    层层调用

    UserAction类代码如下:

    package com.swift.action;
    
    import com.opensymphony.xwork2.ActionSupport;
    import com.swift.service.UserService;
    
    public class UserAction extends ActionSupport {
        private UserService userService;
        public void setUserService(UserService userService) {
            this.userService = userService;
        }
    
    
        @Override
        public String execute() throws Exception {
            System.out.println("action..................");
            userService.add();
            return NONE;
        }
    
    }

    UserService类代码如下:

    package com.swift.service;
    
    import com.swift.dao.UserDao;
    
    public class UserService {
    
        private UserDao userDao;
        public void setUserDao(UserDao userDao) {
            this.userDao = userDao;
        }
        public void add() {
            System.out.println("UserService.................");
            userDao.add();
        }
        
    }

    UserDao接口代码如下:

     package com.swift.dao; public interface UserDao { public void add(); } 

    UserDao接口的实现类UserDaoImplement代码如下:

    package com.swift.dao;
    
    import org.springframework.orm.hibernate5.HibernateTemplate;
    
    import com.swift.entity.User;
    
    public class UserDaoImplements implements UserDao{
        private HibernateTemplate hibernateTemplate;
        public void setHibernateTemplate(HibernateTemplate hibernateTemplate) {
            this.hibernateTemplate = hibernateTemplate;
        }
    
        @Override
        public void add() {
            User user=new User();
            user.setUsername("small-fly");
            user.setAddress("War of Mercenaries");
            hibernateTemplate.save(user);
        }
    
    }

    hibernate核心配置文件hibernate.cfg.xml文件代码

    <?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.connection.driver_class">com.mysql.jdbc.Driver</property>
            <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/sw_database</property>
            <property name="hibernate.connection.username">root</property>
            <property name="hibernate.connection.password">root</property> -->
            <property name="hibernate.dialect">org.hibernate.dialect.MySQL57Dialect</property>
            
            
            <property name="hibernate.show_sql">true</property>
         <property name="hibernate.format_sql">true</property>
            <!-- create: 先删表,再建表。 create-drop: 启动时建表,退出前删表。 update: 如果表结构不一致,就创建或更新。 
                validate: 启动时验证表结构,如果不致就抛异常。 -->
            <property name="hibernate.hbm2ddl.auto">update</property>
            
    
            <!--指定映射文件,可映射多个映射文件 -->
            <mapping resource="User.hbm.xml"></mapping>
        </session-factory>
    </hibernate-configuration>

    hibernate映射文件代码如下:

    <?xml version="1.0" encoding='UTF-8'?>     
    <!DOCTYPE hibernate-mapping PUBLIC 
        "-//Hibernate/Hibernate Mapping DTD 3.0//EN"
        "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">
        <!-- 实体类映射文件 -->
    <hibernate-mapping>
    
        <class name="com.swift.entity.User" table="t_user">
            <!-- 主键 -->
            <id name="uid">
                <generator class="native"></generator>
            </id>
            <!-- 其他属性 -->
            <property name="username"/>
            <property name="address"/>
        </class>
        
    </hibernate-mapping>

    运行action出现问题

    原因,jar包问题,重新整理OK的SSH jar包合集
