Spring+SpringMVC+MyBatis框架搭建

写此博客是为了更好的理解和巩固SSM框架搭建的步骤

一、建立数据库

1.结构如下，数据库表名为user



2.项目的结构图

二、Maven项目的搭建

1.新建Maven项目，选择webapp项目



2.填写项目的项目名之类的



Maven项目在这里就建好了，但是目录缺少点什么，index.jsp也会报错

把项目编码改为UTF-8



修改Jdk版本





在pom.xml中添加javaee的jar包

<dependency>
<groupId>javax</groupId>
<artifactId>javaee-api</artifactId>
<version>7.0</version>
</dependency>

现在项目就创建好了，下面开始进行项目框架的配置和整合

三、框架搭建和整合

1.编辑pom.xml添加依赖包

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion>

2.接着在resources中添加4个需要的文件

jdbc.properties 管理数据库数据的

log4j.properties 管理日志的

spring-mvc.xml SpringMVC的配置文件

spring-mybatis.xml spring和mybatis整合的配置文件

jdbc.properties.xml

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc\:mysql\://localhost\:3306/testu?useUnicode\=true&characterEncoding\=UTF-8
jdbc.username=root
jdbc.password=admin
jdbc.initialSize=0
jdbc.maxActive=20
jdbc.maxIdle=20
jdbc.minIdle=0
jdbc.maxWait=60000

log4j..properties.xml

#定义LOG输出级别
log4j.rootLogger=INFO,Console,File
#定义日志输出目的地为控制台
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.Target=System.out
#可以灵活地指定日志输出格式，下面一行是指定具体的格式
log4j.appender.Console.layout = org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=[%c] - %m%n

#文件大小到达指定尺寸的时候产生一个新的文件
log4j.appender.File = org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File = logs/ssm.log
#定义文件最大大小
log4j.appender.File.MaxFileSize = 10MB
# 输出所以日志，如果换成DEBUG表示输出DEBUG以上级别日志
log4j.appender.File.Threshold = ALL
log4j.appender.File.layout = org.apache.log4j.PatternLayout
log4j.appender.File.layout.ConversionPattern =[%p] [%d{yyyy-MM-dd HH\:mm\:ss}][%c]%m%n

spring-mvc.xml

<?xml version="1.0" encoding="UTF-8"?>

spring-mybatis.xml

<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource" />
</bean>
</beans>

还有web.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"

<!-- 此处可以可以配置成*.do，对应struts的后缀习惯 -->
<url-pattern>*.do</url-pattern>
</servlet-mapping>
<welcome-file-list>
<welcome-file>/index.jsp</welcome-file>
</welcome-file-list>

</web-app>

由于用的是jetty来进行项目的运行所以需要在WEB-INF 目录下添加一个jetty-env.xml文件

jetty-env.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Configure PUBLIC "-//Jetty//Configure//EN"
"http://www.eclipse.org/jetty/configure.dtd">

<Configure id="ws" class="org.eclipse.jetty.webapp.WebAppContext">
<New id="DSTest" class="org.eclipse.jetty.plus.jndi.Resource">
<Arg>jdbc/DBHrms</Arg>
<Arg>
<New class="org.apache.commons.dbcp.BasicDataSource">
<Set name="url">jdbc:mysql://localhost:3306/ssm?useUnicode=true&characterEncoding=utf8</Set>
<Set name="username">root</Set>
<Set name="password">admin</Set>
<Set name="validationQuery">SELECT 1 from dual</Set>
</New>
</Arg>
</New>
</Configure>

到这里配置文件就基本配置完成了
