这篇文章主要介绍了Springboot整合MybatisPlus的实现过程解析,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下
1、pom文件
<?xml version="1.0" encoding="UTF-8"?><project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.cun</groupId> <artifactId>plus</artifactId> <version>0.0.1-SNAPSHOT</version> <packaging>jar</packaging> <name>plus</name> <description>Demo project for Spring Boot</description> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.5.14.RELEASE</version> <relativePath/> <!-- lookup parent from repository --> </parent> <properties> <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding> <project.reporting.outputEncoding>UTF-8</project.reporting.outputEncoding> <java.version>1.8</java.version> </properties> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> <scope>runtime</scope> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> <!-- https://mvnrepository.com/artifact/com.baomidou/mybatis-plus-boot-starter --> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>2.3</version> </dependency> <!-- 代码生成器默认使用如下模版引擎 --><!-- <dependency> <groupId>org.apache.velocity</groupId> <artifactId>velocity-engine-core</artifactId> <version>2.0</version> </dependency>--> <!-- freemarker 模板引擎 --> <dependency> <groupId>org.freemarker</groupId> <artifactId>freemarker</artifactId> <version>2.3.28</version> </dependency> <!--Druid--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid-spring-boot-starter</artifactId> <version>1.1.10</version> </dependency> </dependencies> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build></project>
2、创建CodeGenerator.java
package com.cun.plus;import com.baomidou.mybatisplus.enums.IdType;import com.baomidou.mybatisplus.generator.AutoGenerator;import com.baomidou.mybatisplus.generator.config.DataSourceConfig;import com.baomidou.mybatisplus.generator.config.GlobalConfig;import com.baomidou.mybatisplus.generator.config.PackageConfig;import com.baomidou.mybatisplus.generator.config.StrategyConfig;import com.baomidou.mybatisplus.generator.config.rules.DbType;import com.baomidou.mybatisplus.generator.config.rules.NamingStrategy;import com.baomidou.mybatisplus.generator.engine.FreemarkerTemplateEngine;public class CodeGenerator { public static void main(String[] args) { //1. 全局配置 GlobalConfig config = new GlobalConfig(); config.setActiveRecord(false) // 是否支持AR模式 .setAuthor("len") // 作者 .setOutputDir(".\\src\\main\\java") // 生成路径 .setFileOverride(true) // 文件覆盖 .setIdType(IdType.AUTO) // 主键策略 .setServiceName("I%sService") // 设置生成的service接口的名字的首字母是否为I // IUserService .setBaseResultMap(true) .setBaseColumnList(true); //2. 数据源配置 DataSourceConfig dsConfig = new DataSourceConfig(); dsConfig.setDbType(DbType.MYSQL) // 设置数据库类型 .setDriverName("com.mysql.jdbc.Driver") .setUrl("jdbc:mysql://localhost:3306/mydatab?useSSL=true&verifyServerCertificate=false&allowMultiQueries=true&useUnicode=true&characterEncoding=UTF-8") .setUsername("root") .setPassword("lqq74561"); //3. 策略配置 //配置要生成的表的表名 String[] tableName = {"system_power_type","system_admin","company","power_api","power_action","power_action_api","power_action_group","power_admin_group","power_group"}; StrategyConfig stConfig = new StrategyConfig(); stConfig.setCapitalMode(true) //全局大写命名 .setDbColumnUnderline(true) // 指定表名 字段名是否使用下划线 .setNaming(NamingStrategy.underline_to_camel) // 数据库表映射到实体的命名策略 .setTablePrefix("tb_") .setInclude(tableName); // 生成的表 //4. 包名策略配置 PackageConfig pkConfig = new PackageConfig(); pkConfig.setParent("com.cun.plus") .setMapper("mapper") .setService("service") .setController("controller") .setEntity("entity") .setXml("mapper"); //5. 整合配置 AutoGenerator ag = new AutoGenerator(); ag.setGlobalConfig(config) .setDataSource(dsConfig) .setStrategy(stConfig) .setPackageInfo(pkConfig); //6. 执行 ag.setTemplateEngine(new FreemarkerTemplateEngine()); ag.execute(); }}
3、在application.yml中配置mybatis-plus
#mybatis-plusmybatis-plus: #xml mapper-locations: classpath:/mapper/*Mapper.xml #bean typeAliasesPackage: com.cun.plus.entity global-config: # 3:"UUID"; id-type: 3 field-strategy: 2 db-column-underline: true key-generator: com.baomidou.mybatisplus.incrementer.OracleKeyGenerator logic-delete-value: 1 logic-not-delete-value: 0 sql-injector: com.baomidou.mybatisplus.mapper.LogicSqlInjector configuration: map-underscore-to-camel-case: true cache-enabled: false #JdbcTypeForNull jdbc-type-for-null: 'null'
4、创建MybatisPlusConfig.java文件
package com.cun.plus.conf;import org.mybatis.spring.annotation.MapperScan;import org.springframework.context.annotation.Configuration;@Configuration@MapperScan("com.cun.plus.mapper")public class MybatisPlusConfig {}
其他
Wrapper：MP内置条件封装器。
Sql分析器：（MybatisPlusConfig.java中）
/** * SQL执行效率插件 */@Bean@Profile({"dev","test"})// 设置 dev test 环境开启public PerformanceInterceptor performanceInterceptor() { return new PerformanceInterceptor();}
