SSM框架整合配置

SSM框架整合

1.导入相关pom依赖

<dependencies>
        
        <dependency>
            <groupId>junitgroupId>
            <artifactId>junitartifactId>

        dependency>
        
        <dependency>

        dependency>
    dependencies>
    

2.静态资源的释放（注意）

    <build>
        <resources>
            <resource>
                <directory>src/main/javadirectory>
                <includes>
                    <include>**/*.propertiesinclude>
                    <include>**/*.xmlinclude>
                includes>
                <filtering>falsefiltering>
            resource>
            <resource>
                <directory>src/main/resourcesdirectory>
                <includes>
                    <include>**/*.propertiesinclude>
                    <include>**/*.xmlinclude>
                includes>
                <filtering>falsefiltering>
            resource>
        resources>
    build>

3.建立基本的结构

• Controller层

• Mapper层（相当于Dao层）

• Pojo层

• Service层
  

4.XML配置文件

Mybatis配置文件

<configuration>
    
    
    <typeAliases>
        <package name="com.lit.pojo"/>
    typeAliases>
    
    <mappers>
        <mapper resource="com.lit.mapper.BookMapper.xml"/>
    mappers>
configuration>

5.Log4J配置文件

#将等级为DEBUG的日志信息输出到console和file这两个目的地，console和file的定义在下面的代码
