SSM整合环境搭建（ajax异步请求）

1、新建web工程

2、MyBatis和Spring整合

2.1、导入MyBatis的jar包

• 包含mybatis的包（必须导入）

• mybatis包中的lib目录下的依赖包（可选，最好是全部导入）

asm-7.1
cglib-3.3.0
commons-logging-1.2
javassist-3.26.0-GA
log4j-1.2.17
log4j-api-2.13.0
log4j-core-2.13.0
mybatis-3.5.4
ognl-3.2.12
slf4j-api-1.7.30
slf4j-log4j12-1.7.30

2.2、导入数据库的驱动jar包

mysql-connector-java-5.1.47

2.3、导入Spring的核心jar包与日志包（核心4+1）

spring-beans-5.1.9.RELEASE
spring-context-5.1.9.RELEASE
spring-core-5.1.9.RELEASE
spring-expression-5.1.9.RELEASE
spring-jcl-5.1.9.RELEASE

2.4、导入AOP相关jar包和AspectJ包

spring-aop-5.1.9.RELEASE
aspectjweaver-1.9.4

2.5、导入Spring对持久层的支持包

JDBC支持

spring-jdbc-5.1.9.RELEASE

事务包

spring-tx-5.1.9.RELEASE

2.6、引入数据源

druid-1.1.10

2.7、编写连接信息（db.properties）

jdbc.driverClassName=com.mysql.jdbc.Driver
jdbc.url=jdbc:mysql://localhost:3306/spring
jdbc.username=root
jdbc.password=root

 

2.8、加入log4j的配置文件（log4j.properties）

　　MyBatis是使用的log4j记录日志

### \u8BBE\u7F6E###
log4j.rootLogger = debug,stdout,D,E
### \u8F93\u51FA\u4FE1\u606F\u5230\u63A7\u5236\u62AC ###
log4j.appender.stdout = org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target = System.out
log4j.appender.stdout.layout = org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern = [%-5p] %d{yyyy-MM-dd HH:mm:ss,SSS} method:%l%n%m%n

### \u8F93\u51FADEBUG \u7EA7\u522B\u4EE5\u4E0A\u7684\u65E5\u5FD7\u5230=E://logs/error.log ###
log4j.appender.D = org.apache.log4j.DailyRollingFileAppender
log4j.appender.D.File = E://logs/log.log
log4j.appender.D.Append = true
log4j.appender.D.Threshold = DEBUG 
log4j.appender.D.layout = org.apache.log4j.PatternLayout
log4j.appender.D.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

### \u8F93\u51FAERROR \u7EA7\u522B\u4EE5\u4E0A\u7684\u65E5\u5FD7\u5230=E://logs/error.log ###
log4j.appender.E = org.apache.log4j.DailyRollingFileAppender
log4j.appender.E.File =E://logs/error.log 
log4j.appender.E.Append = true
log4j.appender.E.Threshold = ERROR 
log4j.appender.E.layout = org.apache.log4j.PatternLayout
log4j.appender.E.layout.ConversionPattern = %-d{yyyy-MM-dd HH:mm:ss}  [ %t:%r ] - [ %p ]  %m%n

 

2.9、构建lib包的路径

2.10、导入spring-mybatis整合jar包

mybatis-spring-2.0.3

2.11、编写Spring的配置文件

 　　一般spring的配置文件都命名为applicationContext.xml

<?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-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">



</beans>

 

2.12、数据源信息交给Spring管理

　　因为配置数据源连接的信息交给Spring管理，所以没有必要编写mybatis的配置信息。

<?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-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!--    加载外部文件-->
    <context:property-placeholder location="classpath:db.properties"/>

    <!--    配置数据源-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driverClassName}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>

</beans>

 

2.13、配置SqlSessionFactory

<?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-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!--    加载外部文件-->
    <context:property-placeholder location="classpath:db.properties"/>

    <!--    配置数据源-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driverClassName}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
    <!--    配置SQLSessionFactory 加载mybatis的配置文件-->
    <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--        mybatis设置 开启驼峰命名-->
        <property name="configuration">
            <bean class="org.apache.ibatis.session.Configuration">
                <property name="mapUnderscoreToCamelCase" value="true"/>
            </bean>
        </property>
    </bean>

</beans>

 

2.14、加载MyBatis的映射文件

　　以前mybatis的映射文件在mybatis的配置文件中加载，此时可以交给Spring价值啊，所以mybatis中不用编写Mappers标签，至此完全没有mybatis配置文件存在的必要，因此在SSM项目中没有mybatis的配置文件。

<?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: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-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!--    加载外部文件-->
    <context:property-placeholder location="classpath:db.properties"/>
    <!--    开启包扫描-->
    <context:component-scan base-package="top.ftime.wk.service"/>
    <!--    配置数据源-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driverClassName}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
    <!--    配置SQLSessionFactory 加载mybatis的配置文件-->
    <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--        mybatis设置 开启驼峰命名-->
        <property name="configuration">
            <bean class="org.apache.ibatis.session.Configuration">
                <property name="mapUnderscoreToCamelCase" value="true"/>
            </bean>
        </property>
    </bean>
    <!--    加载mybatis的映射文件-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="top.ftime.wk.mapper"/>
    </bean>

</beans>

 

2.15、配置事务相关

<?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-4.2.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    <!--    加载外部文件-->
    <context:property-placeholder location="classpath:db.properties"/>

    <!--    配置数据源-->
    <bean id="dataSource" class="com.alibaba.druid.pool.DruidDataSource">
        <property name="driverClassName" value="${jdbc.driverClassName}"/>
        <property name="url" value="${jdbc.url}"/>
        <property name="username" value="${jdbc.username}"/>
        <property name="password" value="${jdbc.password}"/>
    </bean>
    <!--    配置SQLSessionFactory 加载mybatis的配置文件-->
    <bean id="sessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource"/>
        <!--        mybatis设置 开启驼峰命名-->
        <property name="configuration">
            <bean class="org.apache.ibatis.session.Configuration">
                <property name="mapUnderscoreToCamelCase" value="true"/>
            </bean>
        </property>
    </bean>
    <!--    加载mybatis的映射文件-->
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="top.ftime.wk.mapper"/>
    </bean>

    <!--    配置事务管理器-->
    <bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
        <property name="dataSource" ref="dataSource"/>
    </bean>
    <!--    开启事务驱动-->
    <tx:annotation-driven/>
</beans>

3.8、配置视图解析器

如果页面是jsp的话 必须使用试视图解析器 我们的页面不是jsp 视图解析器没有作用 所以不用加

4、配置web.xml文件

4.1、加载Spring的配置文件

<?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"
