需要在spring boot 扫描 加上@MapperScan(basePackages= "com.yulece.app.management.user.provide.repositories") 进行手动扫描

应该是数据源不对。你可以先检查数据源

检查两个项目是否有冲突的内容

你的注入方式有问题吧@Resource annotation requires a single-arg method: public org.apache.ibatis.session.SqlSession必须要有唯一个生成sqlSession的公共方法。

检查springboot的所需的jar包是否完整

看一下 genericDao 这个类的路径是否能被spring 扫描到,或者spring是否正常加载的

检查下你扫描包的路径和你的 配置类的包

generatorConfig.xml网上有很多例子,看看你的各种路径对吗,如果你用maven引包应该没啥

SpringBoot集成Mybatis遇到问题

小白一个,第一次使用springboot,想用mybatis来做dao层框架,按网上资料进行了一下配置但是出现了一个错误,我不知道我的配置错在哪儿,麻烦大神帮忙指导一下,谢谢: application.properties配置如下: mybatis.mapper-locations=classpath:mapper/mapper/*Mapper.xml mybatis.config-location=classpath:mapper/sqlMapConfig.xml spring.datasource.url=jdbc:mysql://127.0.0.1:3306/test spring.datasource.driver-class-name=com.mysql.jdbc.Driver spring.datasource.username=root spring.datasource.password=root 接着是sqlMapConfig.xml: <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configurationPUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <settings> <setting name="mapUnderscoreToCamelCase" value="true" /> </settings> </configuration> 然后是mapp.xml的配置 <mapper namespace="com.tky.test.dao.UserMapper"> <select id="getUser" resultType="com.tky.test.emit.User"> select * from user </select> </mapper> sercive层代码如下: package com.tky.test.service; import java.util.List; import javax.annotation.Resource; import org.springframework.stereotype.Service; import com.tky.test.dao.UserMapper; import com.tky.test.emit.User; @Service(value="userService") public class UserServiceImpl implements UserService{ @Resource private UserMapper userMapper; @Override public List<User> findUser() { List<User> findAll = userMapper.findAll(); return findAll; } } 然后是Mapper接口的代码: package com.tky.test.dao; import java.util.List; import com.tky.test.emit.User; public interface UserMapper { public List<User> findAll(); } 在下面是controller层的: @RestController(value="userController") public class UserController { @Resource private UserService userService; @RequestMapping("my") public List<User> getMy(){ List<User> findUser = userService.findUser(); return findUser; } } 最后是springboot的主函数代码: import org.apache.ibatis.session.SqlSessionFactory; import org.mybatis.spring.SqlSessionFactoryBean; import org.mybatis.spring.annotation.MapperScan; import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.context.annotation.Bean; @SpringBootApplication @MapperScan(value="com.tky.test.dao") public class Driver { public static void main(String[] args) { //项目入口 SpringApplication.run(Driver.class,args); } @Bean public SqlSessionFactory sessionFactory() throws Exception{ SqlSessionFactory sqlSessionFactory = new SqlSessionFactoryBean().getObject(); return sqlSessionFactory; } } 最后的报错信息很长是这样的: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userController': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userService': Injection of resource dependencies failed; nested exception is org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'userMapper' defined in file [D:\work\tky_workspace\Test_SpringBoot\target\classes\com\tky\test\dao\UserMapper.class]: Unsatisfied dependency expressed through bean property 'sqlSessionFactory'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'sessionFactory' defined in com.tky.test.Driver: Bean instantiation via factory method failed; nested exception is org.springframework.beans.BeanInstantiationException: Failed to instantiate [org.apache.ibatis.session.SqlSessionFactory]: Factory method 'sessionFactory' threw exception; nested exception is java.lang.IllegalArgumentException: Property 'dataSource' is required 有没有大神能看明白的帮忙指导一下,谢谢

springboot mybatis 整合后怎么答应输出sql语句

关于springboot mybatis 整合后,我想看到mybatis的sql语句日志输出,贴出我的Application.java代码 @SpringBootApplication //等价于@ComponentScan+@EnableAutoConfiguration+@Configuration @MapperScan("cn.no7player.mapper") public class Application { private static Logger logger = Logger.getLogger(Application.class); @Bean @ConfigurationProperties(prefix="spring.datasource") public DataSource dataSource() { return new org.apache.tomcat.jdbc.pool.DataSource(); } @Bean public SqlSessionFactory sqlSessionFactoryBean() throws Exception { SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean(); sqlSessionFactoryBean.setDataSource(dataSource()); PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver(); sqlSessionFactoryBean.setMapperLocations(resolver.getResources("classpath:/mybatis/*.xml")); return sqlSessionFactoryBean.getObject(); } @Bean public PlatformTransactionManager transactionManager() { return new DataSourceTransactionManager(dataSource()); } /** * Start */ public static void main(String[] args) { SpringApplication.run(Application.class, args); logger.info("SpringBoot Start Success"); } }

求大神帮忙看一下:IDEA 中springboot maven mybatis整合项目 启动报错

``` UserController.java文件: @RestController @RequestMapping("/springboot") public class UserController { @Resource(name="userInfoService") UserInfoService userInfoService; @RequestMapping("printUserInfo/{userName}") public String printUserInfo(@PathVariable String userName) { return userInfoService.printUserInfo(userName); } } ``` ``` UserInfoService.java文件:

UserInfoTableDao createUserInfo(UserInfoTableDao userInfoTableDao) { UserInfoTableDao userInfoTableDaoTmp = userInfoMapper.insert(userInfoTableDao); return userInfoTableDaoTmp; } } ``` ``` UserInfoMapper.java文件 @Repository @Mapper public interface UserInfoMapper { public UserInfoTableDao query(UserInfoTableCriteria userInfoTableCriteria); // public List<UserInfoTableDao> queryList(UserInfoTableCriteria userInfoTableCriteria); public UserInfoTableDao insert(UserInfoTableDao userInfoTableDao); public UserInfoTableDao update(UserInfoTableDao userInfoTableDao); public int

``` ``` 文件中namespace,resultType,parameterType对应的文件路径也是完全正确的。 UserInfoMapper.xml文件: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"

Springboot启动报错 一个是找不到url 一个是找不到dao

## 之前一直启动都没有问题,今天突然发现启动不了 ![图片说明](https://img-ask.csdn.net/upload/201910/10/1570671612_490949.jpg) ## 然后我把启动的位置改成@SpringBootApplication(exclude = DataSourceAutoConfiguration.class) ``` package

springboot+mybatis切换数据源问题

# 问题描述 springboot+mybatis想实现oracle和Mysql数据库切换,目前用 Mysql作为 主数据源时, 可以正常查询;用Oracle作为主数据源时,也可以正常查询;目前想实现,Mysql作为主数据源时,也可以切换到另外一个数据源。 # 相关代码如下 ## 创建数据源 ### 创建Mysql数据源 ``` @Bean(name = "dataSource") @Primary public ComboPooledDataSource createDataSource() throws PropertyVetoException { ComboPooledDataSource comboPooledDataSource = new ComboPooledDataSource(); comboPooledDataSource.setDriverClass(jdbcDriver); comboPooledDataSource.setJdbcUrl(jdbcUrl); comboPooledDataSource.setUser(jdbcUsername); comboPooledDataSource.setPassword(jdbcPassword); //连接关闭不自动提交 comboPooledDataSource.setAutoCommitOnClose(false); return comboPooledDataSource; } @Bean(name="sqlSessionFactory") @Primary public SqlSessionFactoryBean createSqlSessionFactoryBean(@Qualifier("dataSource") DataSource dataSource) throws IOException { SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean(); sqlSessionFactoryBean.setConfigLocation(new ClassPathResource(mybatisConfigFilePath)); PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver(); String packageSearchPath = PathMatchingResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX + mapperPath; sqlSessionFactoryBean.setMapperLocations(resolver.getResources(packageSearchPath)); sqlSessionFactoryBean.setDataSource(dataSource); sqlSessionFactoryBean.setTypeAliasesPackage(entityPackage); return sqlSessionFactoryBean; } ``` ### 创建oracle数据源 ``` @Bean(name="oracleDataSource") public ComboPooledDataSource createOracleDataSource() throws PropertyVetoException { ComboPooledDataSource comboPooledOracleDataSource = new ComboPooledDataSource(); comboPooledOracleDataSource.setDriverClass(oracleJdbcDriver); comboPooledOracleDataSource.setJdbcUrl(oracleJdbcUrl); comboPooledOracleDataSource.setUser(oracleJdbcUser); comboPooledOracleDataSource.setPassword(oracleJdbcPassword); comboPooledOracleDataSource.setAutoCommitOnClose(false); return comboPooledOracleDataSource; } @Bean(name="oracleSqlSessionFactory") public SqlSessionFactoryBean createSqlSessionFactoryBean(@Qualifier("oracleDataSource") DataSource oracleDataSource) throws IOException { SqlSessionFactoryBean sqlSessionFactoryBean = new SqlSessionFactoryBean(); sqlSessionFactoryBean.setConfigLocation(new ClassPathResource(mybatisConfigFilePath)); PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver(); String packageSearchPath = PathMatchingResourcePatternResolver.CLASSPATH_ALL_URL_PREFIX + oracleMapperPath; sqlSessionFactoryBean.setMapperLocations(resolver.getResources(packageSearchPath)); sqlSessionFactoryBean.setDataSource(oracleDataSource); sqlSessionFactoryBean.setTypeAliasesPackage(entityPackage); return sqlSessionFactoryBean; } ``` ## 事物管理代码段 ``` @Autowired @Qualifier("dataSource") private DataSource dataSource; @Autowired @Qualifier("oracleDataSource") private DataSource oracleDataSource; @Bean(name="localMysql") public PlatformTransactionManager localMysqlManager(){ return new DataSourceTransactionManager(dataSource); } @Bean(name="localOracle") public PlatformTransactionManager oracleManager(){ return new DataSourceTransactionManager(oracleDataSource); } ``` ## 切换数据源代码段 ``` @Override @Transactional(value = "localOracle") public List<Map> listOracle() { return helloOracleDao.listHello(); } ``` # 问题 感觉数据源创建什么的都没问题,但是最后一步切换不生效,不知道什么问题,还请大神赐教

springboot整合mybatis-plus无法映射xml文件

异常信息: ```org.apache.ibatis.binding.BindingException: Invalid bound statement (not found)``` 异常原因排除: 1. 项目正常启动 2. mybaits-plus配置mapper.xml扫描没问题 ```xml mybatis-plus: # 配置扫描xml mapper-locations: classpath*:mapper/*/*Mapper.xml # 实体扫描,多个package用逗号或者分号分隔 type-aliases-package: org.cnplo.control.modules.admin.domain ``` 3. mapperscan扫描mapper正常 4.mybatis-plus的配置文件 MybatisPlusConfig配置 ```java @Configuration @MapperScan("org.cnplo.control.modules.*.mapper") public class MybatisPlusConfig { /** * 乐观锁插件 */ @Bean public OptimisticLockerInterceptor optimisticLockerInterceptor() { return new OptimisticLockerInterceptor(); } /** * mybatis-plus分页插件 */ @Bean public PaginationInterceptor paginationInterceptor() { return new PaginationInterceptor(); } } ``` DruidDataSourceConfig配置 ```java @Configuration public class DruidDataSourceConfig { /** * @return DruidDataSource */ @Bean @ConfigurationProperties(prefix = "spring.datasource") public DruidDataSource druidDataSource() { return new DruidDataSource(); } /** * 配置事物管理器 */ @Bean public DataSourceTransactionManager transactionManager() { return new DataSourceTransactionManager(druidDataSource()); } } ``` 项目正常启动,执行数据库请求的时候异常BindingException。请问这是什么问题,大胆猜测是哪个jar包升级引起的,还请大佬们不吝赐教 ``` <properties> <java.version>1.8</java.version> <json.version>1.2.54</json.version> <druid.version>1.1.20</druid.version> <swagger.version>2.7.0</swagger.version> <mybatisplus.version>3.3.1.tmp</mybatisplus.version> </properties> <dependencies> <!--web--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <!--lombok--> <dependency> <groupId>org.projectlombok</groupId> <artifactId>lombok</artifactId> <optional>true</optional> </dependency> <!--druid--> <dependency> <groupId>com.alibaba</groupId> <artifactId>druid</artifactId> <version>${druid.version}</version> </dependency> <dependency> <groupId>mysql</groupId> <artifactId>mysql-connector-java</artifactId> </dependency> <!-- mybatisplus与springboot整合 --> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus-boot-starter</artifactId> <version>${mybatisplus.version}</version> </dependency> <dependency> <groupId>com.baomidou</groupId> <artifactId>mybatis-plus</artifactId> <version>${mybatisplus.version}</version> </dependency> <dependency> <groupId>org.mybatis.spring.boot</groupId> <artifactId>mybatis-spring-boot-autoconfigure</artifactId> <version>1.3.2</version> </dependency> <!-- swagger2 rest api start--> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger2</artifactId> <version>${swagger.version}</version> </dependency> <dependency> <groupId>io.springfox</groupId> <artifactId>springfox-swagger-ui</artifactId> <version>${swagger.version}</version> </dependency> <!--json工具--> <dependency> <groupId>com.alibaba</groupId> <artifactId>fastjson</artifactId> <version>${json.version}</version> </dependency> <!-- jwt --> <dependency> <groupId>io.jsonwebtoken</groupId> <artifactId>jjwt</artifactId> <version>0.9.1</version> </dependency> <!--redis--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-data-redis</artifactId> </dependency> <!--thymeleaf--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-thymeleaf</artifactId> </dependency> <!--test--> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> <exclusions> <exclusion> <groupId>org.junit.vintage</groupId> <artifactId>junit-vintage-engine</artifactId> </exclusion> </exclusions> </dependency> </dependencies> ```

gradle+spring boot+mybatis+PageHelper 分页无效

被折磨了一天,网上也找了很多解决办法,都不行,求助大神 如果PageHelper 降版本到4.0的话,PageInfo里的属性就全是空的, 直接用PageHelper.startPage(1, 2); 也没用。 ,不废话,直接上代码。 测试类: ``` @RunWith(SpringRunner.class) @SpringBootTest public class UserMappertest { @Autowired private UserMapper userMapper;
