1.ssm框架简介

SSM整合
S：SpringMvc
S:Spring
M:mybatis

2.创建一个MAVEN-Web工程

替换web.xml文件

3.添加jar包依赖


        
    
      org.springframework
      spring-webmvc
      5.2.15.RELEASE
    

    
    
      org.mybatis
      mybatis
      3.5.6
    

    
    
      org.mybatis
      mybatis-spring
      2.0.6
    

    
    
      mysql
      mysql-connector-java
      8.0.28
    

    
    
      com.alibaba
      druid
      1.2.1
    

    
    
      org.projectlombok
      lombok
      1.18.24
    
   
    
      com.fasterxml.jackson.core
      jackson-databind
      2.13.2.2
    
        
    
      javax.servlet
      javax.servlet-api
      4.0.1

4.编写spring配置文件

5.配置web.xml



    
        spring
        org.springframework.web.servlet.DispatcherServlet
        
            contextConfigLocation
            classpath:springmvc.xml
        
    
    
        spring
        /
    
    
        encodingFilter
        org.springframework.web.filter.CharacterEncodingFilter
        
            encoding
            /*
        
    
    
        encodingFilter
        /

6.generator生成代码

（1）依赖

 
    
      org.mybatis.generator
      mybatis-generator-core
      1.4.0

（2）配置文件

（3）测试

public class TestGeneratory {
    public static void main(String[] args) throws Exception {
        List warnings = new ArrayList();
        boolean overwrite = true;
        File configFile = new File("generator.xml");
        ConfigurationParser cp = new ConfigurationParser(warnings);
        Configuration config = cp.parseConfiguration(configFile);
        DefaultShellCallback callback = new DefaultShellCallback(overwrite);
        MyBatisGenerator myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
        myBatisGenerator.generate(null);
    }
}

7.添加sql日志

 
      log4j
      log4j
      1.2.17

若log4j日志报错可以改用 slf4j


      org.slf4j
      slf4j-log4j12
      1.7.30

日志内容

log4j.rootLogger=DEBUG, 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
