SSM整合

1、创建Model

2、导入依赖

3、创建表

CREATE TABLE `t_emp` (
    `emp_id` int(11) NOT NULL AUTO_INCREMENT,
    `emp_name` varchar(20) DEFAULT NULL,
    `age` int(11) DEFAULT NULL,
    `sex` char(1) DEFAULT NULL,
    `email` varchar(50) DEFAULT NULL,
    PRIMARY KEY (`emp_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

4、配置web.xml

  
  
    CharacterEncodingFilter
    org.springframework.web.filter.CharacterEncodingFilter
    
    
      encoding
      UTF-8
    
    
    
      forceEncoding
      true
    
  
  
    CharacterEncodingFilter
    /*
  


  
  
    HiddenHttpMethodFilter
    org.springframework.web.filter.HiddenHttpMethodFilter
  
  
    HiddenHttpMethodFilter
    /*
  


  
  
    DispatcherServlet
    org.springframework.web.servlet.DispatcherServlet
    
    
      contextConfigLocation
      classpath:SpringMVC.xml
    
    1
  
  
    DispatcherServlet
    /
  


  
  
    contextConfigLocation
    classpath:Spring.xml
  
  
  
  
  
    org.springframework.web.context.ContextLoaderListener
  

5、创建SpringMVC的配置文件并配置

6、创建Spring的配置文件并配置

7、搭建MyBatis环境

7.1 创建属性文件jdbc.properties

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

7.2 创建Mybatis核心配置文件mybatis-config.xml

7.3 创建Mapper接口和映射文件

mapper接口

public interface EmployeeMapper {
List getEmployeeList();
}

映射文件




    
        select * from t_emp
    

7.4 创建日志文件log4j.xml
