SSM搭建(个人笔记)
一，SSM的搭建
1，配置相关的依赖pom.xml文件
<!-- 声明一个通用的版本参数 --> <properties> <spring.version>4.3.17.RELEASE</spring.version> </properties> <dependencies> <!-- spring的相关依赖包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-tx</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-beans</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>${spring.version}</version> </dependency> <!-- 导入druid数据源包 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.18</version> </dependency> <!-- 导入数据库包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.38</version> </dependency> <!-- 导入spring的web包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${spring.version}</version> </dependency> <!-- springmvc的包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>${spring.version}</version> </dependency> <!-- 导入aop的包 --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.10</version> </dependency> <!-- mybatis 核心包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.2.8</version> </dependency> <!-- mybatis整合spring连接包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.0</version> </dependency> <!-- 测试包 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>4.12</version> <scope>test</scope> </dependency> <!-- 日志 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <!-- c标签包 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- jsp --> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>4.0.1</version> <scope>provided</scope> </dependency> <dependencies>
2，配置spring
2.1 在web.xml中使用listener加载spring
2.2 加载spring的配置文件
<!-- 加载spring --> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <!-- 加载spring的配置文件 --> <context-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:applicationContext.xml</param-value> </context-param>
3，配置springmvc
3.1 在springmvc.xml中进行配置
3.1.1<!-- 注解驱动 -->
3.1.2<!-- 扫描包 -->
3.1.3<!-- 视图解析器 -->
<?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-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd "> <!-- 注解驱动 --> <mvc:annotation-driven></mvc:annotation-driven> <!-- 扫描包 --> <context:component-scan base-package="com.zhrt.controller"></context:component-scan> <!-- 视图解析器 --> <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/"></property> <property name="suffix" value=".jsp"></property> </bean> </beans>
3.2 在web.xml中配置核心控制器
3.2.2在web.xml中配置springmvc映射
3.2.2在web.xml中配置解决提交乱码
<!-- 配置springmvc核心控制器 --> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <!-- 加载配置springmvc文件 --> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath:springmvc.xml</param-value> </init-param> <!-- 启动加载 --> <load-on-startup>1</load-on-startup> </servlet> <!-- 映射 --> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping>
<!-- 解决提交乱码 --> <filter> <filter-name>CharacterEncodingFilter</filter-name> <filter-class>org.springframework.web.filter.CharacterEncodingFilter</filter-class> <!-- 设置过滤器中的属性值 --> <init-param> <param-name>encoding</param-name> <param-value>UTF-8</param-value> </init-param> <!-- 启动过滤器 --> <init-param> <param-name>forceEncoding</param-name> <param-value>true</param-value> </init-param> </filter> <!-- 过滤所有请求 --> <filter-mapping> <filter-name>CharacterEncodingFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping>
4，在applicationContext.xml中配置数据源
5，在applicationContext.xml中加载mybatis
6，在applicationContext.xml中配置事务
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" xmlns:tx="http://www.springframework.org/schema/tx" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation=" http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.3.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.3.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.3.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd "> <!-- 配置数据源 --> <bean id="DataSource" class="com.alibaba.druid.pool.DruidDataSource"> <property name="DriverClassName" value="com.mysql.jdbc.Driver"></property> <property name="url" value="jdbc:mysql://localhost:3306/ssm?useUnicode=TRUE&characterEncoding=UTF-8"></property> <property name="username" value="root"></property> <property name="password" value="123"></property> </bean> <!-- 加载mybatis --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!-- 注入数据源 --> <property name="dataSource" ref="DataSource"></property> <!-- 加载配置文件 --> <property name="ConfigLocation" value="classpath:sqlconfig.xml"></property> </bean> <!-- 加载事务 --> <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <!-- 注入数据源 --> <property name="dataSource" ref="DataSource"></property> </bean> <!-- 声明事务 --> <tx:advice id="txadvice" transaction-manager="transactionManager"> <tx:attributes> <tx:method name="insert*" propagation="REQUIRED"/> </tx:attributes> </tx:advice> <!-- aop --> <aop:config> <!-- 切点 --> <aop:pointcut expression="execution(* com.zhrt.service.*.*(..))" id="cutpoint"/> <!-- 融合切点 --> <aop:advisor advice-ref="txadvice" pointcut-ref="cutpoint"/> </aop:config>
二，编写具体代码
1，创建controller，service，dao(mapper)，pojo包
2，创建数据库
3，前端页面
三，mybatis的逆向工程
1，打开逆向工程的项目
2，修改数据库链接属性
3，修改实体类生成的包名
4，修改映射文件
5，修改接口mapper
6，指定逆向生成的表
7，运行程序自动生成
8，将生成mapper和pojo拷贝到项目中
9，在applicationContext.xml中扫描mapper
<!-- 扫描mapper文件 --> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!-- 注入sqlSessionFactory --> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property> <!-- 指定扫描包的路径 --> <property name="basePackage" value="com.zhrt.mapper"></property> </bean>
10，在service中使用mapper（要配置@service，在applicationContext.xml（spring）中扫描service层）
<!-- 扫描service层 --> <context:component-scan base-package="com.zhrt.service"></context:component-scan>
四，解决乱码问题
