SSM整合系列之 SSM项目整合
Spring、SpringMVC和Mybatis已经是非常成熟的框架了，使用该框架开发已有些时日了，从今天开始呢就对用此框架开发的过程进行一系列的总结，旨在个人总结中提升自己，同时能帮到需要的人就更好了（大牛可忽略此文）。本文将着重介绍项目的搭建整合。
项目git地址：https://github.com/gitcaiqing/SSM_DEMO.git
1 Maven Web项目创建
2 SSM整合
项目结构如下图：
2.1 web.xml配置
webapp下创建WEB-INF然后创建web.xml文件，文件内容如下：

classpath*:spring/*.xml,classpath*:servlet/*.xml
org.springframework.web.context.ContextLoaderListener
encodingFilter
org.springframework.web.filter.CharacterEncodingFilter
encoding

2.3、数据库连接和Log4j配置
src-main-resource下创建config文件夹，然后创建jdbc.properties文件，文件内容如下：
#连接驱动
jdbc.driverClassName=com.mysql.jdbc.Driver
#主库
jdbc.url = jdbc\:mysql\://localhost\:3306/db_ssmdemo?useUnicode\=true&characterEncoding\=UTF-8&allowMultiQueries\=true
jdbc.username = root
jdbc.password = 123456
jdbc.initialSize=2
jdbc.maxActive=5
jdbc.maxIdle=5
jdbc.minIdle=1
jdbc.validationQuery=select 1
src-main-resource创建文件log4j.properties，文件内容如下：
log4j.rootLogger = DEBUG,stdout,A1,A2
### STDOUT
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern =[%d{yyyy-MM-dd HH:mm:ss}][%p] %m %n
### INFO
log4j.appender.A1 = org.apache.log4j.DailyRollingFileAppender
log4j.appender.A1.File =../logs/info.log
log4j.appender.A1.Append = true
log4j.appender.A1.Threshold =INFO
log4j.appender.A1.layout = org.apache.log4j.PatternLayout
log4j.appender.A1.layout.ConversionPattern =[%d{yyyy-MM-dd HH:mm:ss}][%p] %m %n
###ERROR
log4j.appender.A2 = org.apache.log4j.DailyRollingFileAppender
log4j.appender.A2.File =../logs/error.log
log4j.appender.A2.Append = true
log4j.appender.A2.Threshold =ERROR
log4j.appender.A2.layout = org.apache.log4j.PatternLayout
log4j.appender.A2.layout.ConversionPattern =[%d{yyyy-MM-dd HH:mm:ss}][%p] %m %n
log4j.logger.com.ibatis=DEBUG
log4j.logger.com.ibatis.common.jdbc.SimpleDataSource=DEBUG
log4j.logger.com.ibatis.common.jdbc.ScriptRunner=DEBUG
log4j.logger.com.ibatis.sqlmap.engine.impl.SqlMapClientDelegate=DEBUG
log4j.logger.org.mybatis=DEBUG
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
log4j.logger.java.sql.ResultSet=DEBUG
2.4Spring配置
src-main-resource下创建spring文件夹，然后创建applicationContext.xml文件
2.5数据源配置
spring文件加下创建dataAccessContext.xml文件
数据库、事务配置
2.6 Mybatis配置
spring文件加下创建mybatis.xml文件，该文件为spring和mybatis整合内容
classpath:sql/*.xml
2.7 整合SpringMVC
src-main-resource下创建servlet文件夹，然后创建spring-mvc.xml文件
UTF-8
104857600
4096
2.8创建index.jsp页面
在webapp创建index.jsp页面
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
Insert title here
index.jsp
2.9 创建一个测试Controller,类为HelloController
package com.ssm.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.ResponseBody;
@Controller
@RequestMapping("test")
public class HelloController {
@RequestMapping("hello")
@ResponseBody
public String hello() {
return "hello";
}
}
访问http://IP地址:端口号/SSM_DEMO/test/hello，即可查看返回值，正常返回，说明项目搭建成功
