ssm整合

1.创建maven 项目：创建maven-archetype-webapp

2.在main里面添加java之后在mark Directory as 设置为(source root)与resource之后在mark Directory as 设置为(resources root)

3.注入依赖：

​ 1> servlet依赖

​ 2>Spring-context(包含beans,core ,aop,context)

​ 3>aop需要的aspectj

​ 4>Spring-web,Springwebmvc,commons-fileupload,jackson

​ 5>mybatis,mysql

​ 6>mybatis-spring ,spring-jdbc

​ 7>spring-tx,durid(阿里巴巴的连接池)

4.配置web.xml

将头改为：

配置监听器

    
        org.springframework.web.context.ContextLoaderListener
    

配置spring需要加载的文件

    
        contextConfigLocation
        classpath:spring.xml
    

配置springmvc需要加载的文件

    
        mvc
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath:springMvc.xml
        
        0
    
    
        mvc
        /
    

配置过滤器，设置字符为UTF-8

    
        encodingFilter
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            utf-8
        
    
    
        encodingFilter
        /*
    

5.在resource资源下创建spring.xml,springMvc.xml,db.properties,mybaties.xml

spring.xml

springMvc.xml

db.properties

mysql.driver=com.mysql.cj.jdbc.Driver
mysql.url=jdbc:mysql://localhost:3306/test_ssm?serverTimezone=UTC
mysql.username=root
mysql.password=root

mybaties.xml
