SSM整合配置文件——完整版

SSM框架整合

Spring+SpringMVC+Mybatis，
简称SSM，是后台程序员在编程道路上必备的三大框架，也是当前最流行的框架组合，减少代码的冗余，其中Mybatis更是避免了几乎所有的JDBC代码和手动设置参数以及获取结果集！

第一步：创建Maven项目

第二步：在pom.xml导入所需依赖

        <dependencies>  <dependency>     <groupId>junit</groupId>     <artifactId>junit</artifactId>     <version>4.12</version> </dependency>  <dependency>     <groupId>mysql</groupId>     <artifactId>mysql-connector-java</artifactId>     <version>5.1.47</version> </dependency>   <dependency>     <groupId>com.mchange</groupId>     <artifactId>c3p0</artifactId>     <version>0.9.5.2</version> </dependency>  <dependency>     <groupId>javax.servlet</groupId>     <artifactId>servlet-api</artifactId>     <version>2.5</version> </dependency> <dependency>     <groupId>javax.servlet.jsp</groupId>     <artifactId>jsp-api</artifactId>     <version>2.2</version> </dependency> <dependency>     <groupId>javax.servlet</groupId>     <artifactId>jstl</artifactId>     <version>1.2</version> </dependency>  <dependency>     <groupId>org.aspectj</groupId>     <artifactId>aspectjweaver</artifactId>     <version>1.8.13</version> </dependency>  <dependency>     <groupId>org.mybatis</groupId>     <artifactId>mybatis</artifactId>     <version>3.5.2</version> </dependency> <dependency>     <groupId>org.mybatis</groupId>     <artifactId>mybatis-spring</artifactId>     <version>2.0.2</version> </dependency>  <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-webmvc</artifactId>     <version>5.1.9.RELEASE</version> </dependency> <dependency>     <groupId>org.springframework</groupId>     <artifactId>spring-jdbc</artifactId>     <version>5.1.9.RELEASE</version> </dependency> <dependency>     <groupId>org.projectlombok</groupId>     <artifactId>lombok</artifactId>     <version>1.18.18</version> </dependency>    </dependencies>        <build>  <resources>     <resource>  <directory>src/main/resources</directory>  <includes>      <include>**/*.properties</include>      <include>**/*.xml</include>  </includes>  <filtering>true</filtering>     </resource>     <resource>  <directory>src/main/java</directory>  <includes>      <include>**/*.properties</include>      <include>**/*.xml</include>  </includes>  <filtering>true</filtering>     </resource> </resources>    </build>

然后依次配置各类xml文件

配置Mybatis-config.xml文件

<configuration><settings><setting name="logImpl" value="STDOUT_LOGGING"/><setting name="mapUnderscoreToCamelCase" value="true"/></settings><typeAliases><package name="com.wumao.pojo"/></typeAliases><mappers><mapper class="com.wumao.mapper.UserMapper"/></mappers></configuration>

配置jdbc.properties文件

jdbc.driver=com.mysql.jdbc.Driver#如果使用的是mysql8.0+，增加一个时区的设置； &serverTimezone=Asia/Shanghaijdbc.url=jdbc:mysql://localhost:3306/ssmbuild?useSSL=true&useUnicode=true&characterEncoding=utf8jdbc.username=rootjdbc.password=123456

配置spring-mapper.xml文件
