在使用spring boot集成mybatis-plus的过程中遇到的问题

如图,

首先我放xml的包的是没问题的，而是引入的架包和配置问题，问题配置如下

解决方法：请将mybatis-plus改成mybatis,mybatis,mybtis,重要的说三遍，必要的架包如下

<dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring- boot-starter</artifactId></dependency><!-- https://mvnrepository.com/artifact/com.baomidou/mybatis-plus --><dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus</artifactId> <version>2.1.9</version></dependency><dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-autoconfigure</artifactId> <version>1.3.2</version></dependency>

注意第一个是mybatis-spring-boot-start ,不是mybatisplus-spring-boot-start还要在mybatis配置文件里声明MybatisSqlSessionFactoryBean，至此问题解决

@Configurationpublic class MybatisPlusConfig { @Autowired private DataSource dataSource; @Autowired private MybatisProperties properties; @Autowired private ResourceLoader resourceLoader = new DefaultResourceLoader(); @Autowired(required = false) private Interceptor[] interceptors; @Autowired(required = false) private DatabaseIdProvider databaseIdProvider; /** * mybatis-plus分页插件 */ @Bean public PaginationInterceptor paginationInterceptor() { PaginationInterceptor page = new PaginationInterceptor(); page.setDialectType("mysql"); return page; } /** * 这里全部使用mybatis-autoconfigure 已经自动加载的资源。不手动指定 * 配置文件和mybatis-boot的配置文件同步 * @return */ @Bean public MybatisSqlSessionFactoryBean mybatisSqlSessionFactoryBean() { MybatisSqlSessionFactoryBean mybatisPlus = new MybatisSqlSessionFactoryBean(); mybatisPlus.setDataSource(dataSource); mybatisPlus.setVfs(SpringBootVFS.class); if (StringUtils.hasText(this.properties.getConfigLocation())) { mybatisPlus.setConfigLocation(this.resourceLoader.getResource(this.properties.getConfigLocation())); } mybatisPlus.setConfiguration(properties.getConfiguration()); if (!ObjectUtils.isEmpty(this.interceptors)) { mybatisPlus.setPlugins(this.interceptors); } MybatisConfiguration mc = new MybatisConfiguration(); mc.setDefaultScriptingLanguage(MybatisXMLLanguageDriver.class); mybatisPlus.setConfiguration(mc); if (this.databaseIdProvider != null) { mybatisPlus.setDatabaseIdProvider(this.databaseIdProvider); } if (StringUtils.hasLength(this.properties.getTypeAliasesPackage())) { mybatisPlus.setTypeAliasesPackage(this.properties.getTypeAliasesPackage()); } if (StringUtils.hasLength(this.properties.getTypeHandlersPackage())) { mybatisPlus.setTypeHandlersPackage(this.properties.getTypeHandlersPackage()); } if (!ObjectUtils.isEmpty(this.properties.resolveMapperLocations())) { mybatisPlus.setMapperLocations(this.properties.resolveMapperLocations()); } return mybatisPlus; }}

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
