mybatis plus的逆向工程及基本使用

yml的配置

mybatis-plus:
  mapper-locations: classpath*:com/gwq/movie/**/xml/*Mapper.xml
  global-config:
    id-type: 0
    db-column-underline: false
    refresh-mapper: true

spring:
  datasource:
    url: jdbc:mysql://127.0.0.1:3306/meetingfilm?autoReconnect=true&useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=CONVERT_TO_NULL&useSSL=false&serverTimezone=UTC
    username: root
    password: root
    filters: log4j,wall,mergeStat

俩个配置类

package com.next.jiangzh.springbootdemo.config;

import com.alibaba.druid.pool.DruidDataSource;
import lombok.Data;
import lombok.extern.slf4j.Slf4j;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Configuration;

import java.sql.SQLException;

@Data
@Configuration
@ConfigurationProperties(prefix = "spring.datasource")
public class DruidProperties {

    private String url = "jdbc:mysql://127.0.0.1:3306/mooc_demo?autoReconnect=true&useUnicode=true&characterEncoding=utf8&zeroDateTimeBehavior=CONVERT_TO_NULL&useSSL=false&serverTimezone=UTC";

    private String username = "root";

    private String password = "1234567";

    private String driverClassName = "com.mysql.cj.jdbc.Driver";

    private Integer initialSize = 2;

    private Integer minIdle = 1;

    private Integer maxActive = 20;

    private Integer maxWait = 60000;

    private Integer timeBetweenEvictionRunsMillis = 60000;

    private Integer minEvictableIdleTimeMillis = 300000;

    private String validationQuery = "SELECT 'x'";

    private Boolean testWhileIdle = true;

    private Boolean testOnBorrow = false;

    private Boolean testOnReturn = false;

    private Boolean poolPreparedStatements = true;

    private Integer maxPoolPreparedStatementPerConnectionSize = 20;

    private String filters = "stat";

    public void config(DruidDataSource dataSource) {

        dataSource.setUrl(url);
        dataSource.setUsername(username);
        dataSource.setPassword(password);

        dataSource.setDriverClassName(driverClassName);
        dataSource.setInitialSize(initialSize);     //定义初始连接数
        dataSource.setMinIdle(minIdle);             //最小空闲
        dataSource.setMaxActive(maxActive);         //定义最大连接数
        dataSource.setMaxWait(maxWait);             //最长等待时间

        // 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒
        dataSource.setTimeBetweenEvictionRunsMillis(timeBetweenEvictionRunsMillis);

        // 配置一个连接在池中最小生存的时间，单位是毫秒
        dataSource.setMinEvictableIdleTimeMillis(minEvictableIdleTimeMillis);
        dataSource.setValidationQuery(validationQuery);
        dataSource.setTestWhileIdle(testWhileIdle);
        dataSource.setTestOnBorrow(testOnBorrow);
        dataSource.setTestOnReturn(testOnReturn);

        // 打开PSCache，并且指定每个连接上PSCache的大小
        dataSource.setPoolPreparedStatements(poolPreparedStatements);
        dataSource.setMaxPoolPreparedStatementPerConnectionSize(maxPoolPreparedStatementPerConnectionSize);

        try {
            dataSource.setFilters(filters);
        } catch (SQLException e) {
            e.printStackTrace();
        }
    }

}
