首先是maven的依赖：pom.xml
<?xml version="1.0" encoding="UTF-8"?> <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

其中加入了mybatis generator的插件
接下来是web.xml文件：
<?xml version="1.0" encoding="UTF-8"?> <web-app version="3.0" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"> <display-name>xxx</display-name> <!-- 404错误拦截 --> <error-page> <error-code>404</error-code> <location>/error404.jsp</location> </error-page> <!-- 500错误拦截 --> <error-page> <error-code>500</error-code> <location>/error500.jsp</location> </error-page> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param> <!-- 解决post乱码问题的过滤器 --> <filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <init-param> <param-name>encoding</param-name> <param-value>utf-8</param-value> </init-param> </filter> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- shiro过滤器配置--> <filter> <filter-name>shiroFilter</filter-name> <filter-class>org.springframework.web.filter.DelegatingFilterProxy</filter-class> </filter> <filter-mapping> <filter-name>shiroFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 加载spring容器 --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 防止Spring内存溢出监听器 --> <listener> <listener-class>org.springframework.web.util.IntrospectorCleanupListener</listener-class> </listener> <!-- 配置前端控制器 --> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/spring-mvc.xml</param-value> </init-param> <load-on-startup>1</load-on-startup> <async-supported>true</async-supported><!--设置是否启用异步支持--> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!--会话超时配置（单位为分钟）--> <session-config><!--如果某个会话在一定时间未被访问，则服务器可以扔掉以节约内存--> <session-timeout>120</session-timeout> </session-config> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </web-app>
web.xml中加载了spring的总配置文件：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:p="http://www.springframework.org/schema/p" xmlns:context="http://www.springframework.org/schema/context" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd "> <!-- 引入属性文件 --> <context:property-placeholder location="classpath*:*.properties" /> <!-- 配置扫描包路径--> <context:component-scan base-package="com.xxx"> <context:exclude-filter expression="org.springframework.stereotype.Controller" type="annotation" /><!-- 将Controller的注解排除掉，在spring-mvc.xml单独扫描Controller注解 --> </context:component-scan> <!-- 使用annotation定义事务 --> <tx:annotation-driven transaction-manager="transactionManager" /> <import resource="spring/spring-mybatis.xml"/> </beans>
其中又引入了spring-mybatis.xml文件：
<?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:aop="http://www.springframework.org/schema/aop" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.0.xsd" > <bean id="log-filter" class="com.alibaba.druid.filter.logging.Log4jFilter"> <property name="resultSetLogEnabled" value="true" /> </bean> <!-- 配置数据源 --> <bean name="dataSource" class="com.alibaba.druid.pool.DruidDataSource" init-method="init" destroy-method="close"> <!-- <property name="driverClassName" value="${jdbc.driverClassName}" /> --> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}" /> <property name="password" value="${jdbc.password}" /> <property name="initialSize" value="${jdbc.initialSize}" /> <property name="minIdle" value="${jdbc.minIdle}" /> <property name="maxActive" value="${jdbc.maxActive}" /> <property name="maxWait" value="${jdbc.maxWait}" /> <property name="timeBetweenEvictionRunsMillis" value="${jdbc.timeBetweenEvictionRunsMillis}" /> <property name="minEvictableIdleTimeMillis" value="${jdbc.minEvictableIdleTimeMillis}" /> <property name="validationQuery" value="${jdbc.validationQuery}" /> <property name="testWhileIdle" value="${jdbc.testWhileIdle}" /> <property name="testOnBorrow" value="${jdbc.testOnBorrow}" /> <property name="testOnReturn" value="${jdbc.testOnReturn}" /> <property name="removeAbandoned" value="${jdbc.removeAbandoned}" /> <property name="removeAbandonedTimeout" value="${jdbc.removeAbandonedTimeout}" /> <!-- <property name="logAbandoned" value="${jdbc.logAbandoned}" /> --> <property name="filters" value="${jdbc.filters}" /> <!-- 关闭abanded连接时输出错误日志 --> <property name="logAbandoned" value="true" /> <property name="proxyFilters"> <list> <ref bean="log-filter"/> </list> </property> <!-- 监控数据库 --> <!-- <property name="filters" value="stat" /> --> <!-- <property name="filters" value="mergeStat" />--> </bean> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <property name="mapperLocations" > <list> <value>classpath:com/xxx/data/mapper/*.xml</value> </list> </property> </bean> <bean id="sqlSessionTemplate" class="org.mybatis.spring.SqlSessionTemplate"> <constructor-arg index="0" ref="sqlSessionFactory" /> </bean> <!-- DAO接口所在包名，Spring会自动查找其下的类 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.xxx.data.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> </bean> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> </beans>
然后是springmvc的配置文件：spring-mvc.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:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd"> <!-- 配置视图解析器 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <!-- 使用前缀和后缀 --> <property name="prefix" value="/WEB-INF/views/"></property> <property name="suffix" value=".jsp"></property> </bean> <!-- 使用组件扫描的方式可以一次扫描多个Controller --> <context:component-scan base-package="com.xxx.controller"></context:component-scan> <mvc:annotation-driven /> <!-- 静态资源处理 --> <mvc:resources mapping="/resources/**" location="/resources/" /> <!--配置上传文件数据解析器 --> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver"> <property name="maxUploadSize"> <value>5120000</value> </property> </bean> </beans>
剩下些其他的配置文件有：
1.database.properties
jdbc.driverClass = com.mysql.jdbc.Driver jdbc.url = jdbc:mysql://localhost:3306/xxx?serverTimezone=UTC jdbc.username = root jdbc.password = root jdbc.initialSize=3 jdbc.minIdle=2 jdbc.maxActive=60 jdbc.maxWait=60000 jdbc.timeBetweenEvictionRunsMillis=60000 jdbc.minEvictableIdleTimeMillis=30000 jdbc.validationQuery=SELECT ‘x‘ jdbc.testWhileIdle=true jdbc.testOnBorrow=false jdbc.testOnReturn=false jdbc.poolPreparedStatements=true jdbc.maxPoolPreparedStatementPerConnectionSize=20 jdbc.removeAbandoned=true jdbc.removeAbandonedTimeout=120 jdbc.logAbandoned=false jdbc.filters=stat
2.log4j.properties
### set log levels ###
log4j.rootLogger = DEBUG,Console,File
### 输出到控制台 ###
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= %d{ABSOLUTE} %5p %c{1}:%L - %m%n
### 输出到日志文件 ###
log4j.appender.File=org.apache.log4j.RollingFileAppender
#指定输出目录
log4j.appender.File.File=${project}/WEB-INF/logs/app.log
log4j.appender.File.DatePattern=_yyyyMMdd‘.log‘
#定义文件最大大小
log4j.appender.File.MaxFileSize=10MB
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,SSS}][%c]%m%n
3.如果有用mybatis generator的话需要以下配置文件：generatorConfig.xml
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE generatorConfiguration PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN" "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd"> <generatorConfiguration> <!-- 数据库配置文件 --> <properties resource="database.properties" /> <!--指定特定数据库的jdbc驱动jar包的位置--> <classPathEntry location="E:\\maven\\repo\\mysql\\mysql-connector-java\\5.1.25\\mysql-connector-java-5.1.25.jar"/> <!-- context:生成一组对象的环境 id:必选，上下文id，用于在生成错误时提示 defaultModelType:指定生成对象的样式 1，conditional：类似hierarchical,除了如果一个实体类只包含一个字段,则不会单独生成此实体类; 2，flat：所有内容（主键，blob）等全部生成在一个对象中； 3，hierarchical：主键生成一个XXKey对象(key class)，Blob等单独生成一个对象，其他简单属性在一个对象中(record class) targetRuntime: 1，MyBatis3：默认的值，生成基于MyBatis3.x以上版本的内容，包括XXXBySample； 2，MyBatis3Simple：类似MyBatis3，只是不生成XXXBySample； introspectedColumnImpl：类全限定名，用于扩展MBG --> <context id="mysqlContext" defaultModelType="flat" targetRuntime="MyBatis3Simple"> <!-- 生成的Java文件的编码 --> <property name="javaFileEncoding" value="UTF-8" /> <!-- 自动识别数据库关键字，默认false，如果设置为true，根据SqlReservedWords中定义的关键字列表； 一般保留默认值，遇到数据库关键字（Java关键字），使用columnOverride覆盖 --> <property name="autoDelimitKeywords" value="true" /> <!-- 格式化java代码 --> <property name="javaFormatter" value="org.mybatis.generator.api.dom.DefaultJavaFormatter" /> <!-- 格式化XML代码 --> <property name="xmlFormatter" value="org.mybatis.generator.api.dom.DefaultXmlFormatter" /> <!-- beginningDelimiter和endingDelimiter：指明数据库的用于标记数据库对象名的符号，比如ORACLE就是双引号，MYSQL默认是`反引号； --> <property name="beginningDelimiter" value="`"/> <property name="endingDelimiter" value="`"/> <!-- 注释规则 --> <commentGenerator> <property name="suppressDate" value="true"/> <property name="suppressAllComments" value="true" /> </commentGenerator> <!-- 数据库连接 --> <jdbcConnection driverClass="${jdbc.driverClass}" connectionURL="${jdbc.url}" userId="${jdbc.username}" password="${jdbc.password}" /> <!--指定生成的类型为java类型，避免数据库中number等类型字段 --> <javaTypeResolver> <!-- true：使用BigDecimal对应DECIMAL和 NUMERIC数据类型 false：默认, scale>0;length>18：使用BigDecimal; scale=0;length[10,18]：使用Long； scale=0;length[5,9]：使用Integer； scale=0;length<5：使用Short； --> <property name="forceBigDecimals" value="false"/> </javaTypeResolver> <!-- 数据库的生成配置 --> <!--自动生成的实体的存放包路径 --> <javaModelGenerator targetPackage="com.xxx.pojo" targetProject="src/main/java" > <property name="enableSubPackages" value="true"/> <property name="trimStrings" value="true"/> </javaModelGenerator> <!--自动生成的*Mapper.xml文件存放路径 --> <sqlMapGenerator targetPackage="com.xxx.data.mapper" targetProject="src/main/java" > <property name="enableSubPackages" value="true"/> </sqlMapGenerator> <!--自动生成的*Mapper.java存放路径 --> <javaClientGenerator targetPackage="com.xxx.data.dao" targetProject="src/main/java" type="XMLMAPPER" > <property name="enableSubPackages" value="true"/> </javaClientGenerator> <!-- 此处往下开始项目设置 --> <!-- user表 --> <table tableName="account" domainObjectName="Account"> <!-- generatedKey用于生成生成主键的方法， 如果设置了该元素，MBG会在生成的<insert>元素中生成一条正确的<selectKey>元素，该元素可选 column:主键的列名； sqlStatement：要生成的selectKey语句，有以下可选项： Cloudscape:相当于selectKey的SQL为： VALUES IDENTITY_VAL_LOCAL() DB2 :相当于selectKey的SQL为： VALUES IDENTITY_VAL_LOCAL() DB2_MF :相当于selectKey的SQL为：SELECT IDENTITY_VAL_LOCAL() FROM SYSIBM.SYSDUMMY1 Derby :相当于selectKey的SQL为：VALUES IDENTITY_VAL_LOCAL() HSQLDB :相当于selectKey的SQL为：CALL IDENTITY() Informix :相当于selectKey的SQL为：select dbinfo(‘sqlca.sqlerrd1‘) from systables where tabid=1 MySql :相当于selectKey的SQL为：SELECT LAST_INSERT_ID() SqlServer :相当于selectKey的SQL为：SELECT SCOPE_IDENTITY() SYBASE :相当于selectKey的SQL为：SELECT @@IDENTITY JDBC :相当于在生成的insert元素上添加useGeneratedKeys="true"和keyProperty属性 --> <generatedKey column="id" sqlStatement="MySql" identity="true" /> </table> <table tableName="role" domainObjectName="Role"> <generatedKey column="id" sqlStatement="MySql" identity="true" /> </table> <table tableName="permission" domainObjectName="Permission"> <generatedKey column="id" sqlStatement="MySql" identity="true" /> </table> <table tableName="account_role" domainObjectName="AccountRole"> </table> <table tableName="role_permission" domainObjectName="RolePermission"> </table> </context> </generatorConfiguration>
