IDEA 模板配置

一、tkMapper通用mapper配置

1 新建配置文件generatorConfig.xml，路径src/main/resources/generator/generatorConfig.xml

xml 复制代码

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
        PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
        "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">

<generatorConfiguration>
    <!--    引入数据库连接配置-->
    <context id="Mysql" targetRuntime="MyBatis3Simple" defaultModelType="flat">
        <property name="beginningDelimiter" value=""></property>
        <property name="endimgDelimiter" value=""></property>
        <!--    配置GeneralDao-->
        <plugin type="tk.mybatis.mapper.generator.MapperPlugin">
            <property name="mappers" value="com.itheima.general.GeneralDao"></property>
        </plugin>

        <!--    配置数据库连接-->
        <jdbcConnection driverClass="com.mysql.cj.jdbc.Driver"
                        connectionURL="jdbc:mysql://localhost:3306/tlias?useUnicode=true;characterEncoding=UTF-8;serverTimezone=Asia/Shangha"
                        userId="root"
                        password="123456">
        </jdbcConnection>

        <!--    配置实体类存放路径-->
        <javaModelGenerator targetPackage="com.itheima.pojo" targetProject="src/main/java"/>

        <!--    配置XML 存放路径-->
        <sqlMapGenerator targetPackage="com.itheima.mapper" targetProject="src/main/resources"/>

        <!--    配置 DAO 存放路径-->
        <javaClientGenerator targetPackage="com.itheima.mapper" targetProject="src/main/java" type="XMLMAPPER"/>

        <!--    配置需要指定生成的数据库和表 %代表所有表-->
        <!--    <table tableName="%">-->
        <!-- mysql 配置  -->
        <!--        <generatedKey column="id" sqlStatement="Mysql" identity="true"/>-->
        <!--    </table>-->
        <!-- 生成指定表   -->
        <table tableName="operate_log">
            <!--   mysql 配置     -->
            <generatedKey column="id" sqlStatement="Mysql" identity="true"></generatedKey>
        </table>
    </context>
</generatorConfiguration>

3. 在工程pom文件添加通用Mapper依赖

pom 复制代码

		<!-- tkMapper通用Mapper工具 -->
		<dependency>
			<groupId>tk.mybatis</groupId>
			<artifactId>mapper-spring-boot-starter</artifactId>
			<version>2.1.5</version>
		</dependency>

3. 在工程pom文件添加tkMapper自动代码生成工具

pom 复制代码

			<!-- tkMapper自动代码生成工具 -->
			<plugin>
				<groupId>org.mybatis.generator</groupId>
				<artifactId>mybatis-generator-maven-plugin</artifactId>
				<version>1.3.5</version>

				<!--     配置资源文件路径    -->
				<configuration>
					<configurationFile>${basedir}/src/main/resources/generator/generatorConfig.xml</configurationFile>
				</configuration>

				<dependencies>
					<!--mysql-->
					<dependency>
						<groupId>mysql</groupId>
						<artifactId>mysql-connector-java</artifactId>
						<version>8.0.27</version>
					</dependency>
					<!--mapper-->
					<!-- https://mvnrepository.com/artifact/tk.mybatis/mapper -->
					<dependency>
						<groupId>tk.mybatis</groupId>
						<artifactId>mapper</artifactId>
						<version>4.1.5</version>
					</dependency>
				</dependencies>
			</plugin>

4. 新建Mapper通用继承接口GeneralDao，路径是src/main/java/com/itheima/general/GeneralDao.java，如下图所示：

java 复制代码

import tk.mybatis.mapper.common.Mapper;
import tk.mybatis.mapper.common.MySqlMapper;

/**
 * 通用接口继承类
 *
 * @author ManolinCoder
 * @date 2024-09-06
 */

public interface GeneralDao<T> extends Mapper<T>, MySqlMapper<T> {
}

5 双击插件运行此插件，自动生成代码，如下图所示：

二、SpringBoot配置文件application.xml模板：

xml 复制代码

# 服务端口号
server:
  port: 8080



# Spring配置
spring:
  application:
    # 服务名称
    name: tlias-web-management

  # 数据库配置
  datasource:
    #驱动类名称
    driver-class-name: com.mysql.cj.jdbc.Driver
    #数据库连接的url
    url: jdbc:mysql://localhost:3306/tlias?useUnicode=true&characterEncoding=UTF-8&autoReconnect=true&failOverReadOnly=false&serverTimezone=Asia/Shanghai
    #连接数据库的用户名
    username: root
    #连接数据库的密码
    password: 123456
  servlet:
    multipart:
      #配置单个文件上传大小限制
      max-file-size: 10MB
      #配置单个请求最大大小的限制 (一次请求中是可以上传多个文件)
      max-request-size: 100MB



#配置mybatis的日志, 指定输出到控制台
mybatis:
  configuration:
    log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
    #开启mybatis的驼峰命名自动映射开关 a_column ------> aCloumn
    map-underscore-to-camel-case: true



# 自定义阿里云OSS配置信息
aliyun:
  oss:
    endpoint: https://oss-cn-guangzhou.aliyuncs.com
    accessKeyId: LTAWYI5tKFYHhSeqEyXM1
    accessKeySecret: sDdFaSAsdDeWYUrDSFDdETwiSOGTDdz3
    bucketName: lsdlflsdnews



#spring事务管理日志
logging:
  level:
    org.springframework.jdbc.support.JdbcTransactionManager: debug

三、Mapper配置文件mybatis-mapper.xml

xml 复制代码

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE mapper
        PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
        "https://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.itheima.mapper.EmpMapper">


</mapper>
