本文详细介绍如何使用Maven整合Spring、Spring MVC和MyBatis（简称SSM），包括配置pom.xml文件、添加Tomcat插件、设置配置文件等内容，并解决常见问题，最后进行项目优化。
Maven整合SSM框架
零、 目录
- Maven整合SSM
- 常见的问题
- 以及一些优化
一、 Maven整合SSM
- 创建webapp工程
- 修改jdk和编译器
配置pom.xml文件 并在pom.xml文件中添加tomcat插件
pom.xml文件中一般需要使用的依赖
<!-- 集中定义依赖版本号 --> <properties> <junit.version>4.12</junit.version> <spring.version>4.2.3.RELEASE</spring.version> <mybatis.version>3.2.8</mybatis.version> <mybatis.spring.version>1.2.2</mybatis.spring.version> <mybatis.paginator.version>1.2.15</mybatis.paginator.version> <mysql.version>5.1.32</mysql.version> <bonecp-spring.version>0.8.0.RELEASE</bonecp-spring.version> <druid.version>1.0.9</druid.version> <mapper.version>2.3.2</mapper.version> <pagehelper.version>3.4.2</pagehelper.version> <jsqlparser.version>0.9.1</jsqlparser.version> <slf4j.version>1.6.4</slf4j.version> <jstl.version>1.2</jstl.version> <servlet-api.version>2.5</servlet-api.version> <jsp-api.version>2.0</jsp-api.version> </properties> <dependencies> <!-- Spring --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>${spring.version}</version> </dependency> <!-- Mybatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>${mybatis.version}</version> </dependency> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>${mybatis.spring.version}</version> </dependency> <dependency> <groupId>com.github.miemiedev</groupId> <artifactId>mybatis-paginator</artifactId> <version>${mybatis.paginator.version}</version> </dependency> <!-- 通用Mapper，所有的单表的代码都不用编写 --> <dependency> <groupId>com.github.abel533</groupId> <artifactId>mapper</artifactId> <version>${mapper.version}</version> </dependency> <!-- Oracle版权问题，maven目录必须自己手动建立 --> <dependency> <groupId>com.oracle</groupId> <artifactId>ojdbc6</artifactId> <version>11.1.0.7.0</version> </dependency> <!-- MySql --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>${mysql.version}</version> </dependency> <!-- 超高性能连接池 --> <dependency> <groupId>com.zaxxer</groupId> <artifactId>HikariCP-java6</artifactId> <version>2.3.9</version> <scope>compile</scope> </dependency> <!-- Apache Shiro 权限架构 --> <dependency> <groupId>org.apache.shiro</groupId> <artifactId>shiro-all</artifactId> <version>1.2.3</version> </dependency> <!-- 分页插件 --> <dependency> <groupId>com.github.pagehelper</groupId> <artifactId>pagehelper</artifactId> <version>${pagehelper.version}</version> </dependency> <dependency> <groupId>com.github.jsqlparser</groupId> <artifactId>jsqlparser</artifactId> <version>${jsqlparser.version}</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-log4j12</artifactId> <version>${slf4j.version}</version> </dependency> <!-- JSP相关 --> <dependency> <groupId>jstl</groupId> <artifactId>jstl</artifactId> <version>${jstl.version}</version> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>servlet-api</artifactId> <version>${servlet-api.version}</version> <scope>provided</scope> </dependency> <dependency> <groupId>javax.servlet</groupId> <artifactId>jsp-api</artifactId> <version>${jsp-api.version}</version> <scope>provided</scope> </dependency> <!-- 字符加密、解密 --> <dependency> <groupId>commons-codec</groupId> <artifactId>commons-codec</artifactId> <version>1.9</version> </dependency> <!-- 数据校验 --> <dependency> <groupId>org.hibernate</groupId> <artifactId>hibernate-validator</artifactId> <version>5.1.3.Final</version> </dependency> <!-- 数据库连接池 --> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.2.1</version> </dependency> <!-- 文件上传 --> <!-- https://mvnrepository.com/artifact/commons-fileupload/commons-fileupload --> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> </dependencies>在pom.xml文件中添加tomcat插件
<!-- tomcat插件配置 --> <build> <plugins> <plugin> <groupId>org.apache.tomcat.maven</groupId> <artifactId>tomcat7-maven-plugin</artifactId> <version>2.2</version> <configuration> <port>8090</port> <path>/</path><!-- 代表缺省值配置 直接访问 --> </configuration> </plugin> </plugins> </build>
添加配置文件
web.xml文件中添加 servlet分发器 、 乱码过滤器 、 引入spring配置文件
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd" > <web-app> <display-name>Archetype Created Web Application</display-name> <!-- 配置默认的欢迎界面 --> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> <!-- 通过监听器listener配置懒加载的spring容器 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:spring/applicationContext*.xml</param-value> </context-param> <!-- spring中自帶 有一個servlet --> <!-- 配置servlet分发器 --> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <!-- 引入springmvc配置文件 --> <param-name>contextConfigLocation</param-name> <param-value>classpath:/spring/springmvc-config.xml</param-value> </init-param> <!-- servlet启动的优先级 值越小优先级越高 --> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>*.action</url-pattern><!-- / --> </servlet-mapping> <!-- 配置Spring自帶的亂碼過濾器 只能过滤post 的乱码--> <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> </web-app>mybatis配置文件

- 修改配置文件中的路径
- 我的目录结构
- 我的目录结构
- 测试
二、常见的问题
- 注意一个端口只能被一个程序使用 ， 所以部署项目时需要先把部署的之前的关掉 ， 或者把即将部署的tomcat端口号改掉
如果maven项目中的jsp页面中el表达式不生效则需要在page标签中添加属性
isELIgnored=“false”
三、优化
- 一般的网站开发中不使用xxx.action这一形式 ， 所以把请求改为直接请求 如：hello.action ->hello ， 把web.xml中请求分发器拦截地址由*.action 改为/ .
但是这样会出现页面访问css等静态资源时被拦截导致不能加载的问题 ， 需要在springmvc-config.xml配置文件中添加
<mvc:default-servlet-handler/>- spring黑心配置文件有原来的一个被分割为3个独立的文件 ， 把mybatis的配置和事务的配置单独抽取出来 ， 目的是为例更好的维护 。
在spring与mybatis整合配置文件中可以直接为包起一个别名 ， 简化了为类起别名的操作 。
<!-- 配置mybatis --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 配置数据源 --> <property name="dataSource" ref = "datassource"></property> <!-- 注入mybatis核心配置文件 --> <property name="configLocation" value="classpath:/mybatis/sqlMapConfig.xml"></property> <!-- 注入映射文件 --> <!-- 如果该目录为空 ， 则会报错 --> <!-- <property name="mapperLocations" value="classpath:/mybatis/mappers/*.xml"></property> --> <!-- 配置包别名 --> <property name="typeAliasesPackage" value="com.tj.ht.pojo" /> </bean>mybatis中开启驼峰自动映射 如： 数据库中标字段aaa_bbb 会自动映射为实体类中的属性aaaBbb
<settings> <!-- 配置缓存 --> <setting name="cacheEnabled" value="true"/> <!-- 配置自动驼峰映射 --> <setting name="mapUnderscoreToCamelCase" value="true"/> </settings>
