我是靠谱客的博主诚心外套，最近开发中收集的这篇文章主要介绍SSH配置流程 (基于注解方式)，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

1.新建一个web project, 记得勾选生成web.xml(以便后期修改)

2.选择到项目右键选择Configure facets/Install Apache Struts(2.x)facet 加载struts的依赖包

3.如上..Configure facets/Install Spring facet 加载spring依赖包

4.如上..Configure facets/Install Hibernate facet 加载hibernate依赖包

如上234点事配置SSH的依赖包, 如果发现有重复出现的依赖包, 挑出版本高的剩下的可以选择右击项目选择Build Path / Configure Build Path将该框架包中的重复包勾选掉

至此, SSH三个框架的依赖包基本配置完毕

5.在src文件夹下面创建jdbc.properties(数据源参数加载文件夹)

模板 :

jdbc.driverClass=com.mysql.jdbc.Driver
jdbc.jdbcUrl=jdbc:mysql://127.0.0.1:3306/数据库名
jdbc.user=xxx
jdbc.password=xxx
c3p0.initialPoolSize=10
c3p0.maxIdleTime=30
c3p0.maxPoolSize=100
c3p0.minPoolSize=10

6.打开src文件夹下的applicationContext.xml文件

模板 :

<?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:mvc="http://www.springframework.org/schema/mvc"
xmlns:p="http://www.springframework.org/schema/p"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd
http://www.springframework.org/schema/aop
http://www.springframework.org/schema/aop/spring-aop-3.1.xsd
http://www.springframework.org/schema/tx
http://www.springframework.org/schema/tx/spring-tx-3.1.xsd
http://www.springframework.org/schema/mvc
http://www.springframework.org/schema/mvc/spring-mvc-3.1.xsd
http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.1.xsd">


<bean class = "org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<value>classpath:jdbc.properties</value>
</property>
</bean>



<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<property name="driverClass" value = "${jdbc.driverClass}"></property>
<property name="jdbcUrl"
value="${jdbc.jdbcUrl}">
</property>
<property name="user" value="${jdbc.user}"></property>
<property name="password" value="${jdbc.password}"></property>

<property name="initialPoolSize" value="${c3p0.initialPoolSize}"></property>

<property name="maxIdleTime" value="${c3p0.maxIdleTime}"></property>

<property name="maxPoolSize" value="${c3p0.maxPoolSize}"></property>

<property name="minPoolSize" value="${c3p0.minPoolSize}"></property>
</bean>

<bean id="sessionFactory" class="org.springframework.orm.hibernate3.annotation.AnnotationSessionFactoryBean">
<property name="dataSource">
<ref bean="dataSource" />
</property>
<property name="hibernateProperties">
<props>
<prop key="hibernate.dialect">
org.hibernate.dialect.MySQLDialect
</prop>
<prop key="hibernate.show_sql">true</prop>
<prop key="hibernate.format_sql">true</prop>
</props>
</property>
<property name="packagesToScan">
<list>
<value>com/xxx/pojo</value>
</list>
</property>

<property name="annotatedClasses">
<list>
<value>com.xxx.pojo.Scenicalert</value>
<value>com.xxx.pojo.Goodkind</value>
</property>
</bean>


<context:annotation-config/>

<context:component-scan base-package="com.xxx.test.dao.impl"/>
<context:component-scan base-package="com.xxx.test.service.impl"/>
<context:component-scan base-package="com.xxx.test.action"/>


<bean id = "hibernateTemplate" class="org.springframework.orm.hibernate3.HibernateTemplate">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>


<bean id="txManager" class="org.springframework.orm.hibernate3.HibernateTransactionManager">
<property name="sessionFactory" ref="sessionFactory"/>
</bean>


<tx:annotation-driven transaction-manager="txManager"/>

</beans>

7.配置日志打印

(1)检查SSH依赖包中是否有log4j-x.x.x.jar和slf4j-log4j12-x.x.x.jar包(如果没有如上依赖包重复出现操作类似, 只不过现在是添加进来)

(2)同时在src文件夹下面创建log4j.properties日志打印配置文件

模板 :

#输出的登记为INFO, 输出类型是console, 输出的目的地是logfile
log4j.rootCategory=INFO,console,logfile

#配置控制台的日志
#输出的目的地是控制台
log4j.appender.console=org.apache.log4j.ConsoleAppender
#设置输出时候的端的布局是哪种布局
log4j.appender.console.layout=org.apache.log4j.PatternLayout
#指定输出的具体信息, 以及具体格式
log4j.appender.console.layout.ConversionPattern= %p %d{yyyy-MM-dd HH:mm:ss} - %t - [%c] : %m %n

#配置指定日志打印日志文件
#配置日志文件的路径
log4j.appender.logfile.File=logs\xxxx_log\xxx.log
#配置日志文件每天产生一个
log4j.appender.logfile=org.apache.log4j.DailyRollingFileAppender
#配置日志文件的日期格式
log4j.appender.logfile.DatePattern=.yyyy-MM-dd
#配置日志文件的布局格式
log4j.appender.logfile.layout=org.apache.log4j.PatternLayout
# 配置日志文件日志打印的格式
log4j.appender.logfile.layout.ConversionPattern=%p %d{yyyy-MM-dd HH:mm:ss} - %t - [%c] : %m %n

(3)在web.xml中加入如下配置

模板 :

<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>classpath:log4j.properties</param-value>
</context-param>
<context-param>
<param-name>log4jRefreshInterval</param-name>
<param-value>3600000</param-value>
</context-param>


<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>

8.修改src文件夹下的struts.xml文件(无需配置action, 使用的是注解方式)

模板 :

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd">
<struts>


<constant name="struts.devMode" value="true"/>


<constant name="struts.objectFactory" value="spring"/>


<constant name="struts.i18n.encoding" value="utf-8"/>


<constant name="struts.i18n.reload" value="false" />


<constant name="struts.configuration.xml.reload" value="false" />

</struts>

至此配置文件基本完成

9.对数据库的表进行逆向工程

(1)转换到数据库连接视图(同时创建一个连接连接到目标数据库)

(2)打开数据库连接(逐层打开)

选到数据库表右键选择Hibernate Reverse Enginering

如下图勾选

至此逆向工程生成实体类完成

10.可以建包写代码

包的结构:

dao层接口 :

模板 :

package com.xxx.text.dao;

public interface UseraccountDao {
public void addUseraccount();
}

dao实现层

模板 :

package com.xxx.test.dao.impl;

import javax.annotation.Resource;

import org.springframework.dao.DataAccessException;
import org.springframework.orm.hibernate3.HibernateTemplate;
import org.springframework.stereotype.Repository;

import com.xxx.pojo.Role;
import com.xxx.pojo.Useraccount;
import com.xxx.text.dao.UseraccountDao;

@Repository(value = "useraccountDaoImpl")
public class UseraccountDaoImpl implements UseraccountDao{

@Resource(name = "hibernateTemplate")
private HibernateTemplate hibernateTemplate;

@Override
public void addUseraccount() {
// TODO Auto-generated method stub
代码.....
}

}

Service 接口层 :

模板 :

package com.xxx.test.service;

public interface RegisterService {
public void RegisterAccount();
}

service实现层 :

模板:

package com.xxx.test.service.impl;

import javax.annotation.Resource;

import org.springframework.stereotype.Service;
import org.springframework.transaction.annotation.Transactional;

import com.xxx.test.service.RegisterService;
import com.xxx.text.dao.UseraccountDao;

@Service(value = "registerServiceImpl")
public class RegisterServiceImpl implements RegisterService{

@Resource(name = "useraccountDaoImpl")
private UseraccountDao useraccountdao;

@Transactional
@Override
public void RegisterAccount() {
// TODO Auto-generated method stub
useraccountdao.addUseraccount();
}

}

action层 :

模板 :

package com.xxx.test.action;

import javax.annotation.Resource;

import org.apache.commons.logging.Log;
import org.apache.commons.logging.LogFactory;
import org.apache.struts2.convention.annotation.Namespace;
import org.apache.struts2.convention.annotation.ParentPackage;
import org.apache.struts2.convention.annotation.Result;
import org.apache.struts2.convention.annotation.Results;
import org.springframework.context.annotation.Scope;
import org.springframework.stereotype.Controller;

import com.xxx.test.service.RegisterService;

@Controller(value = "register.action")
@Scope("prototype")//单例模式
@ParentPackage("struts-default")
@Namespace("/")
@Results({
@Result(name = "success", location="/index.jsp"),
@Result(name = "false", location="/error.jsp")
})
public class RegisterAction {

@Resource(name = "registerServiceImpl")
private RegisterService registerService;

private Log logger = LogFactory.getLog(getClass());

@Action(value = "register")
public String execute(){
registerService.RegisterAccount();
return "success";
}

}

前端页面 :

模板 :

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
%>

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
<html>
<head>
<base href="<%=basePath%>">

<title>My JSP 'index.jsp' starting page</title>
<meta http-equiv="pragma" content="no-cache">
<meta http-equiv="cache-control" content="no-cache">

<body>
