mybatisplus Invalid bound statement (not found)的问题我看网上都说是xml配置问题,浪费了一天的时间,但也有一种可能:
要用mybatisplus的MybatisSqlSessionFactoryBean, 而不是mybatis的SqlSessionFactory,否则会报mybatisplus Invalid bound statement (not found),丫的,大坑。
mybatisplus的主数据源配置如下,其它的数据源将@Primary删除
import com.baomidou.mybatisplus.extension.spring.MybatisSqlSessionFactoryBean;
import org.apache.ibatis.session.SqlSessionFactory;
import org.mybatis.spring.SqlSessionTemplate;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import org.springframework.jdbc.datasource.DataSourceTransactionManager;
import javax.sql.DataSource;
@Configuration
@MapperScan(basePackages = "com.hmg_quartz.mapper.cos", sqlSessionTemplateRef = "db1SqlSessionTemplate")
//此处的basePackages指向的是你存放数据库db1的mapper的包
public class DataSource1Config {
@Bean(name = "db1DataSource")
@ConfigurationProperties(prefix = "spring.datasource.db1")//指向yml配置文件中的数据库配置
@Primary //主库加这个注解,修改优先权,表示发现相同类型bean,优先使用该方法。
public DataSource dbDataSource() {
return DataSourceBuilder.create().build();
}
@Bean(name = "db1SqlSessionFactory")
@Primary
//这里要用mybatisplus的MybatisSqlSessionFactoryBean,
// 而不是mybatis的SqlSessionFactory,否则会报mybatisplus Invalid bound statement (not found),丫的,大坑。
public MybatisSqlSessionFactoryBean dbSqlSessionFactory(@Qualifier("db1DataSource") DataSource dataSource) throws Exception {
MybatisSqlSessionFactoryBean bean = new MybatisSqlSessionFactoryBean();
bean.setDataSource(dataSource);
bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mapper/*.xml"));
//这个的getResources指向的是你的mapper.xml文件,相当于在yml中配置的mapper-locations,此处配置了yml中就不用配置,或者说不会读取yml中的该配置。
return bean;
}
@Bean(name = "db1TransactionManager")
@Primary
public DataSourceTransactionManager dbTransactionManager(@Qualifier("db1DataSource") DataSource dataSource) {
return new DataSourceTransactionManager(dataSource);
}
@Bean(name = "db1SqlSessionTemplate")
@Primary
public SqlSessionTemplate dbSqlSessionTemplate(@Qualifier("db1SqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
return new SqlSessionTemplate(sqlSessionFactory);
}
}
