使用Eclipse搭建SSM框架（Spring + Spring MVC + Mybatis）
1.创建项目
1）打开Eclipse，点击File --> New --> Other
2）输入maven，找到Maven Project
3）然后一直按Next，直到出现一下界面：
4）输入web后点击Aftifact Id为maven-archetype-webapp的选项，然后继续Next
5）然后输入你的Group Id和项目名，点击finish
6）项目创建好之后可能会出现如下情况：
这是因为项目中缺少Tomcat有关jar包导致的，接下来我们就来解决这个问题，右键单击项目，选择Build Path --> Add Library --> Server Runtime,然后点击Next
然后选择你要的Tomcat容器，点击Finish
这个时候问题就解决了
7）更改Dynamic Web Module和jdk版本号。更改之前是这样的：
而我电脑里配的Java环境是jdk1.8的，Tomcat的版本是9.0，可以将Dynamic Web Module版本改成3.1，但是不能直接在上面更改，接下来我就详细讲一下怎么更改这两个版本：
- 首先找到你那个项目所在的路径，打开那个项目文件夹之后找到.settings文件夹，这个在你那里也可能被隐藏，记得打开显示隐藏文件夹的选项
- 然后进入.settings文件夹，找到org.eclipse.wst.common.project.facet.core.xml文件
- 打开文件后改成你对应的版本
更改前》》》》》》》》
更改后》》》》》》》
- 然后回到eclipse中，找到web.xml文件，将其修改为（对应Dynamic Web Module修改后的版本，我这里是3.1）：
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1" metadata-complete="true"> </web-app>
- 第四部修改pom.xml文件（对应修改后的jdk版本），将其修改为：
<build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build>
- 最后右击项目，选择Maven --> Update Project
弹出界面后勾选你当前的项目点击OK即可
2.导入SSM项目所需要的jar包
<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 http://maven.apache.org/maven-v4_0_0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.test</groupId> <artifactId>ssm</artifactId> <packaging>war</packaging> <version>0.0.1-SNAPSHOT</version> <name>ssm Maven Webapp</name> <url>http://maven.apache.org</url> <properties> <!-- Spring版本号 --> <spring.version>4.3.8.RELEASE</spring.version> </properties> <dependencies> <!-- Spring相关包 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-core</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-aop</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-context</artifactId> <version>${spring.version}</version> </dependency> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-web</artifactId> <version>${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-tx</artifactId> <version>${spring.version}</version> </dependency> <!-- AOP相关包 --> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjrt</artifactId> <version>1.8.0</version> </dependency> <dependency> <groupId>org.aspectj</groupId> <artifactId>aspectjweaver</artifactId> <version>1.8.0</version> </dependency> <!-- MyBatis相关包 --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis</artifactId> <version>3.3.0</version> </dependency> <!-- MySQL相关包 --> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <version>5.1.26</version> </dependency> <!-- 数据库连接池 --> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>1.0.20</version> </dependency> <!-- Spring集成MyBatis --> <dependency> <groupId>org.mybatis</groupId> <artifactId>mybatis-spring</artifactId> <version>1.2.3</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-core</artifactId> <version>2.5.2</version> </dependency> <dependency> <groupId>com.fasterxml.jackson.core</groupId> <artifactId>jackson-databind</artifactId> <version>2.5.2</version> </dependency> <!-- JSP标准标签库 --> <dependency> <groupId>javax.servlet</groupId> <artifactId>jstl</artifactId> <version>1.2</version> </dependency> <!-- 日志相关包 --> <dependency> <groupId>log4j</groupId> <artifactId>log4j</artifactId> <version>1.2.17</version> </dependency> <dependency> <groupId>org.slf4j</groupId> <artifactId>slf4j-api</artifactId> <version>1.7.21</version> </dependency> <!-- 单元测试相关包 --> <dependency> <groupId>junit</groupId> <artifactId>junit</artifactId> <version>3.8.1</version> <scope>test</scope> </dependency> <!-- spring对测试框架的简单封装功能 --> <dependency> <groupId>org.springframework</groupId> <artifactId>spring-test</artifactId> <version>${spring.version}</version> <scope>test</scope> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-compiler-plugin</artifactId> <configuration> <source>1.8</source> <target>1.8</target> </configuration> </plugin> </plugins> </build> </project>
3.完善项目结构
相信大家细心的话都会发现，之前创建的项目目录少了一些东西：src/main/java 、src/test/java 、src/test/resources
如果大家的情况和我一样的话，首先我们右击项目，选择 Build Path --> Configure Build Path，进入界面将有错误的文件Remove后点击Apply And Close
然后右击项目，选择 New --> Source Folder
输入名字后点击Finish，依次将缺失的几个补齐
补齐之后，再右击项目，选择 Build Path --> Configure Build Path，进入界面，找到先前补齐的文件，更改Output Folder输出路径
依次更改好之后点击Apply And Close
将以上步骤做好之后，再右击项目 ，选择Properties，找到Deployment Assembly，移除以下两个文件夹后点击Apply And Close
4.创建配置文件
log4j.properties文件：
#USE THIS SETTING FOR OUTPUT MYBATIS`s SQL ON THE CONSOLE
log4j.rootLogger=INFO, Console
#Console
log4j.appender.Console=org.apache.log4j.ConsoleAppender
log4j.appender.Console.layout=org.apache.log4j.PatternLayout
log4j.appender.Console.layout.ConversionPattern=%d [%t] %-5p [%c] - %m%n
log4j.logger.java.sql.ResultSet=INFO
log4j.logger.org.apache=INFO
log4j.logger.java.sql.Connection=DEBUG
log4j.logger.java.sql.Statement=DEBUG
log4j.logger.java.sql.PreparedStatement=DEBUG
mybatis-config.xml文件：
<?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> <setting name="mapUnderscoreToCamelCase" value="true" /> </settings> <!-- 设置别名,对应实体类包名 --> <typeAliases> <package name="com.zqz.pojo" /> </typeAliases> </configuration>
spring-mvc.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: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"> <!-- 启动自动扫描 --> <context:component-scan base-package="com.zqz.*" /> <!-- 注册MVC注解驱动 --> <mvc:annotation-driven /> <!-- 静态资源可访问的设置方式 --> <mvc:default-servlet-handler /> <!-- 配置视图解析器，可以显式设置，也可以不设置，不设置会依据SpringMVC的默认设置 --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/jsp/" /> <property name="suffix" value=".jsp" /> </bean> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"> <property name="messageConverters"> <list> <ref bean="jsonHttpMessageConverter" /> </list> </property> </bean> <bean id="jsonHttpMessageConverter" class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter"> <property name="supportedMediaTypes"> <list> <value>application/json;charset=UTF-8</value> </list> </property> </bean> </beans>
spring-mybatis.xml文件：
<?xml version="1.0" encoding="UTF-8"?> <beans xmlns="http://www.springframework.org/schema/beans" 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.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd "> <!-- 指定扫描的包,对应service的实现类的包 --> <context:component-scan base-package="com.zqz.students.service.impl" /> <!-- 定义数据源Bean --> <!-- Druid --> <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource"> <property name="url" value="jdbc:mysql://localhost:3306/students?useUnicode=true&characterEncoding=UTF-8" /> <property name="username" value="debian-sys-maint" /> <property name="password" value="kzM7KVhkozRHJGp5" /> </bean> <!-- 注册SqlSessionFactoryBean --> <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean"> <property name="dataSource" ref="dataSource" /> <!-- 自动扫描mappers.xml文件 --> <property name="mapperLocations" value="classpath*:com/zqz/dao/*.xml" /> <property name="configLocation" value="classpath:mybatis-config.xml"></property> </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.zqz.dao" /> <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" /> </bean> </beans>
spring-tx.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:context="http://www.springframework.org/schema/context" xmlns:aop="http://www.springframework.org/schema/aop" 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/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"> <!-- 开启AOP注解扫描 --> <aop:aspectj-autoproxy proxy-target-class="true" /> <!-- 事务管理器，依赖于数据源 --> <bean id="txManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager"> <property name="dataSource" ref="dataSource" /> </bean> <!-- 编写通知：对事务进行增强（通知），需要编写对切入点和具体执行事务细节 --> <tx:advice id="txAdvice" transaction-manager="txManager"> <tx:attributes> <!-- 为切入点方法添加事务详情 name：方法名，*表示任意方法名称 propagation：设置传播行为 isolation：设置隔离级别 read-only：是否只读 --> <tx:method name="add*" propagation="REQUIRED" isolation="DEFAULT" read-only="false" rollback-for="Exception" /> <tx:method name="delete*" propagation="REQUIRED" isolation="DEFAULT" read-only="false" rollback-for="Exception" /> <tx:method name="update*" propagation="REQUIRED" isolation="DEFAULT" read-only="false" rollback-for="Exception" /> </tx:attributes> </tx:advice> <!-- 设置AOP，让Spring自动对目标生成代理，需要使用AspectJ表达式 --> <aop:config proxy-target-class="true"> <!-- 切面：整合切入点和通知 --> <aop:advisor advice-ref="txAdvice" pointcut="within(com.zqz.controller..*)" /> </aop:config> </beans>
最后还有web.xml文件：
<?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://xmlns.jcp.org/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" version="3.1" metadata-complete="true"> <context-param> <param-name>contextConfigLocation</param-name> <param-value> classpath*:/spring-mybatis.xml, classpath*:/spring-tx.xml </param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <listener> <listener-class>org.springframework.web.context.request.RequestContextListener</listener-class> </listener> <servlet> <servlet-name>springServlet</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value>classpath*:spring-mvc.xml</param-value> </init-param> <load-on-startup>2</load-on-startup> </servlet> <servlet-mapping> <servlet-name>springServlet</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <session-config> <session-timeout>20</session-timeout> </session-config> </web-app>
到这里整合也就完成了，只剩编写具体的业务代码了
