springMVC环境搭建

首先创建一个maven工程，这里就不多说了。

pom.xml的配置（这里有一些小插件）

<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>

</dependencies>

<build>
<!--配置内部tomcat插件-->
<plugins>
<plugin>
<groupId>org.apache.tomcat.maven</groupId>
<artifactId>tomcat7-maven-plugin</artifactId>
<version>2.2</version>
<configuration>
<path>/</path>
<port>9999</port>
<uriEncoding>UTF-8</uriEncoding>
</configuration>
</plugin>

<!--配置代码生成器插件-->
<plugin>
<groupId>org.mybatis.generator</groupId>
<artifactId>mybatis-generator-maven-plugin</artifactId>
<version>1.3.2</version>
<dependencies>
<dependency>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
<!--此处驱动版本和上面同步-->
<version>5.1.3</version>
</dependency>
</dependencies>
<configuration>
<!--配置文件的路径-->
<configurationFile>src/main/resources/generatorConfig.xml</configurationFile>
<overwrite>true</overwrite>
</configuration>
</plugin>
</plugins>

<!--配置资源打包方式
解决maven 找不到mapper映射文件:放在resources里面不用配置-->
<resources>
<resource>
<directory>src/main/java</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
<resource>
<directory>src/main/resources</directory>
<includes>
<include>**/*.properties</include>
<include>**/*.xml</include>
</includes>
<filtering>false</filtering>
</resource>
</resources>
</build>
再就是配置applicationContext.xml

<?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"
xmlns:tx="http://www.springframework.org/schema/tx"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.2.xsd">

<!-- 配置注解扫描所在的包 -->
<context:component-scan base-package="com.lyh.ssm">
<!-- 代表包含如下注解的类,都交给spring容器管理 -->
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Component" />
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Repository" />
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Service" />
</context:component-scan>

<!-- 加载配数据源配置文件 db.properties -->
<context:property-placeholder location="classpath:db.properties" />

<!-- 配置数据源 ，使用dbcp数据库连接池 -->
<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"
destroy-method="close">
<property name="driverClassName" value="${jdbc.driver}" />
<property name="url" value="${jdbc.url}" />
<property name="username" value="${jdbc.username}" />
<property name="password" value="${jdbc.password}" />
<property name="maxActive" value="30" />
<property name="maxIdle" value="20" />
</bean>
<!-- 事务管理器 （JDBC） -->
<bean id="transactionManager"
class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>

<!-- 启动声明式事务驱动 -->
<tx:annotation-driven transaction-manager="transactionManager" />

<!-- spring 通过 sqlSessionFactoryBean 获取 sqlSessionFactory 工厂类 -->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource"></property>

<!--配置分页助手-->
<property name="plugins">
<array>
<!-- 引入插件类型 -->
<bean class="com.github.pagehelper.PageInterceptor">
<!-- 指定使用的数据库-->
<property name="properties">
<!--因为分页插件支持多种数据库,需指明当前所用数据库 ,helperDialect mysql数据库(方言)-->
<props>
<prop key="helperDialect">mysql</prop>
</props>
</property>
</bean>
</array>
</property>

<!-- 扫描 po 包，使用别名 -->
<property name="typeAliasesPackage" value="com.lyh.ssm.entity"></property>
<!-- 扫描映射文件 -->
<property name="mapperLocations" value="classpath:mapper/*.xml"></property>
</bean>

<!-- 配置扫描 dao 包，动态实现 dao 接口，注入到 spring 容器中, 这里的dao 实际上就是 Mapper接口类 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.lyh.ssm.dao" />
<!-- 注意使用 sqlSessionFactoryBeanName 避免出现spring 扫描组件失效问题 -->
<property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
</bean>

</beans>
这是我个人的目录结构对应上面的配置（如要使用根据需要修改即可）

 

然后就是db.properties和log4j

jdbc.driver=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/springmvc?characterEncoding=utf-8
jdbc.username=root
jdbc.password=123456
-------------------------------------------------------

log4j.appender.stdout.Target = System.out
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = %d{ABSOLUTE} %5p %c{1}:%L - %m%n
log4j.logger.com.lyh.ssm=TRACE
log4j.rootLogger=INFO, stdout
最后springmvc.xml(根据需要进行修改即可)

<?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"
xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop"
xmlns:task="http://www.springframework.org/schema/task"
xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.2.xsd
http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.2.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.2.xsd
http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.2.xsd
http://www.springframework.org/schema/task http://www.springframework.org/schema/task/spring-task-3.2.xsd">

<!-- 配置扫描包 -->
<context:component-scan base-package="com.lyh.ssm.controller">
<!-- 配置扫描 包含Controller 注解的类,相当于是配置了扫描的白名单-->
<context:include-filter type="annotation"
expression="org.springframework.stereotype.Controller" />

</context:component-scan>

<!-- 启动 mvc 注解驱动 -->
<mvc:annotation-driven/>
<!-- 静态资源处理 -->
<mvc:default-servlet-handler/>
<!-- 文件上传 -->
<bean id="multipartResolver"
class="org.springframework.web.multipart.commons.CommonsMultipartResolver">
<!-- 上传文件大小限制10M -->
<property name="maxUploadSize">
<value>10485760</value>
</property>
<!-- 请求的编码格式, 和 jsp 页面一致 -->
<property name="defaultEncoding">
<value>UTF-8</value>
</property>
</bean>
</beans>
