SSM整合thymeleaf
SSM整合
1.引入核心jar包
<dependencies> <!--SpringMVC部分--> <!--这个是springmvc的整体依赖，它依赖于ioc,aop等等，所以aop-ioc-core等等不需要导入--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-webmvc</artifactId> <version>5.3.20</version> </dependency> <!--Spring5整合thymeleaf视图解析--> <dependency> <groupId>org.thymeleaf</groupId> <artifactId>thymeleaf-spring5</artifactId> <version>3.0.15.RELEASE</version> </dependency> <!--文件上传文件的依赖--> <dependency> <groupId>commons-fileupload</groupId> <artifactId>commons-fileupload</artifactId> <version>1.3.1</version> </dependency> <!--springmvc返回json依赖--> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.13.3</version> </dependency> <!--servlet--> <dependency> <groupId>javax.servlet</groupId> <artifactId>javax.servlet-api</artifactId> <version>3.1.0</version> <scope>provided</scope> </dependency> <!--spring部分--> <!--jdbc模板和事务管理--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-jdbc</artifactId> <version>5.3.20</version> </dependency> <!--使用aspectj注解来做AOP--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aspects</artifactId> <version>5.3.20</version> </dependency> <!--spring单元测试,可以在单元测试中自动装配--> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>5.3.20</version> </dependency> <!--mybatis部分--> <!--mybatis核心依赖--> <dependency> <groupId>com.xzixi.framework</groupId> <artifactId>mybatis</artifactId> <version>2.2.2</version> </dependency> <!--spring整合mybatis的jar包--> <dependency> <groupId>org.singledog</groupId> <artifactId>mybatis-spring</artifactId> <version>1.3.3</version> </dependency> <!--数据库部分--> <!--阿里巴巴德鲁伊数据库连接池--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.2.11</version> </dependency> <!--mysql驱动--> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>8.0.28</version> </dependency> <!--日志--> <dependency> <groupId>ch.qos.logback</groupId> <artifactId>logback-classic</artifactId> <version>1.2.11</version> </dependency> <!--单元测试依赖--> <dependency> <groupId>org.junit.jupiter</groupId> <artifactId>junit-jupiter-api</artifactId> <version>5.6.0</version> <scope>test</scope> </dependency> </dependencies>- 1

2.1配置web.xml
主要是
1.spring核心配置文件监听器
2.springmvc前端控制器----servlet
3.字符编码过滤器和restful风格的过滤器

3.创建springmvc.xml配置文件
主要是:
1.Conroller层的包扫描
2.thymeleaf视图解析(这是spring官方推荐的,jsp过时了)
3.静态资源访问和springmvc注解驱动
4.文件上传
<?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:mvc="http://www.springframework.org/schema/mvc" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd "> <!--开启控制器的包扫描--> <context:component-scan base-package="com.raoqi.controller"/> <!--配置thymeleaf视图解析器--> <bean id="viewResolver" class="org.thymeleaf.spring5.view.ThymeleafViewResolver"> <property name="order" value="1" /> <property name="characterEncoding" value="UTF-8"/> <property name="templateEngine"> <bean class="org.thymeleaf.spring5.SpringTemplateEngine"> <property name="templateResolver"> <bean class="org.thymeleaf.spring5.templateresolver.SpringResourceTemplateResolver"> <!-- 视图前缀 --> <property name="prefix" value="/WEB-INF/templates/" /> <!-- 视图后缀 --> <property name="suffix" value=".html"/> <property name="templateMode" value="HTML5"/> <property name="characterEncoding" value="UTF-8" /> </bean> </property> </bean> </property> </bean> <!--将dispactherservlet不能处理的资源路径交给默认的servlet去处理 也就是开启静态资源访问--> <mvc:default-servlet-handler/> <!--开启mvc的注解驱动使springmvc中所有注解功能都生效--> <mvc:annotation-driven /> <!--配置文件上传解析器--> <bean id="multipartResolver" class="org.springframework.web.multipart.commons.CommonsMultipartResolver" /> </beans>- 1

4.创建JDBC.properties配置数据库信息
jdbc.driver=com.mysql.jdbc.Driver jdbc.url=jdbc:mysql://127.0.0.1:3306/test?characterEncoding=utf8&useUnicode=true&useSSL=false&serverTimezone=UTC jdbc.username=root jdbc.password=123456- 1

5.编写Spring的配置文件applicationContext.xml
主要是:1.除了controller层的包扫描
2.德鲁伊数据源
3.spring整合mybatis
4.事务控制
<?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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd "> <!-- 开启包扫描除了控制器其他都扫--> <context:component-scan base-package="com.raoqi"> <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/> </context:component-scan> <!--加载外部数据库配置信息--> <context:property-placeholder location="classpath:jdbc.properties" /> <!--配置数据源，建议使用德鲁伊连接池当然c3p0也可以--> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"> <property name="driverClassName" value="${jdbc.driver}" /> <property name="url" value="${jdbc.url}" /> <property name="username" value="${jdbc.username}"/> <property name="password" value="${jdbc.password}"/> </bean> <!--配置Spring整合mybatis--> <!--在整合中使用SqlSessionFactoryBean来创建SessionFactory工厂--> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <!--指定mybatis核心配置文件--> <property name="configLocation" value="classpath:mybatis-config.xml"/> <!--指定数据源--> <property name="dataSource" ref="dataSource" /> </bean> <!--配置扫描器，将mybatis接口的实现类的扫描加入到IOC容器中--> <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <!--指定Mapper接口包--> <property name="basePackage" value="com.raoqi.mapper"/> </bean> <!--配置Spring的声明式事务，因为使用的mybatis所以使用DataSourceTransactionManager--> <bean id="dataSourceTransactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource"/> </bean> <!--开启Spring事务的注解驱动--> <tx:annotation-driven transaction-manager="dataSourceTransactionManager"/> </beans>- 1

6.配置mybatis的核心配置文件mybatis-config.xml
因为数据源和映射文件都在spring的配置文件中配置了,所以不需要配置这些,只用配置一些常用的设置即可
<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <settings> <!--开启延迟加载--> <setting name="lazyLoadingEnabled" value="true"/> <!--建立mybatis中经典的_命名和java实体类驼峰命名的映射--> <setting name="mapUnderscoreToCamelCase" value="true"/> </settings> <!--配置指定包下别名--> <typeAliases> <!--指定实体类包下的别名，以实体类的类名作为别名不区分大小写--> <package name="com.raoqi.pojo"/> </typeAliases> </configuration>- 1

7.使用mybatis逆向工程来生成java实体类和映射文件和接口
1.在pom.xml中引入mybatis逆向工程的插件
<!--放在pluginManagement同级--> <plugins> <!-- 具体插件，逆向工程的操作是以构建过程中插件形式出现的 --> <plugin> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-maven-plugin</artifactId> <version>1.3.0</version> <!-- 插件的依赖 --> <dependencies> <!-- 逆向工程的核心依赖 --> <dependency> <groupId>org.mybatis.generator</groupId> <artifactId>mybatis-generator-core</artifactId> <version>1.3.2</version> </dependency> <!-- 数据库连接池 --> <dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.2</version> </dependency> <!-- MySQL驱动 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.8</version> </dependency> </dependencies> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>8</source> <target>8</target> </configuration> </plugin> </plugins>- 1

编写逆向工程配置文件，文件名字就叫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> <!-- targetRuntime: 执行生成的逆向工程的版本 MyBatis3Simple: 生成基本的CRUD（清新简洁版） MyBatis3: 生成带条件的CRUD（奢华尊享版） --> <context id="DB2Tables" targetRuntime="MyBatis3"> <commentGenerator> <!--不让注释生成 suppressAllComments--> <property name="suppressAllComments" value="true"/> </commentGenerator> <!-- 数据库的连接信息 --> <jdbcConnection driverClass="com.mysql.jdbc.Driver" connectionURL="jdbc:mysql://127.0.0.1:3306/test?characterEncoding=utf8&useUnicode=true&useSSL=false&serverTimezone=UTC" userId="root" password="123456"> </jdbcConnection> <!-- javaBean的生成策略--> <javaModelGenerator targetPackage="com.raoqi.pojo" targetProject=".\src\main\java"> <property name="enableSubPackages" value="true"/> <property name="trimStrings" value="true"/> </javaModelGenerator> <!-- SQL映射文件的生成策略 --> <sqlMapGenerator targetPackage="com.raoqi.mapper" targetProject=".\src\main\resources"> <property name="enableSubPackages" value="true"/> </sqlMapGenerator> <!-- Mapper接口的生成策略 --> <javaClientGenerator type="XMLMAPPER" targetPackage="com.raoqi.mapper" targetProject=".\src\main\java"> <property name="enableSubPackages" value="true"/> </javaClientGenerator> <!-- 逆向分析的表 --> <!-- tableName设置为*号，可以对应所有表，此时不写domainObjectName --> <!-- domainObjectName属性指定生成出来的实体类的类名 --> <table tableName="student" domainObjectName="Student"/> <table tableName="teacher" domainObjectName="Teacher"/> </context> </generatorConfiguration>- 1
