这两天做SpringBoot整合Mybatis项目的时候，插入时报错：3:45:59.936 DEBUG [http-nio-8080-exec-8] o.s.w.s.m.m.a.ExceptionHandlerExceptionResolver 133 - Resolving exception from handler [public java.lang.String

系统结构：
SpringBoot启动：
@SpringBootApplication(scanBasePackages = "com.example.demo") //@SpringBootApplication(scanBasePackages = "com.example.demo", exclude = DataSourceAutoConfiguration.class) @EnableConfigurationProperties @EnableScheduling @EnableAsync public class ProvideApplication { public static void main(String[] args) throws InterruptedException { ApplicationContext ctx = SpringApplication.run(ProvideApplication.class, args); } }
Mapper的应用DataSource：
`@Configuration@MapperScan(basePackages = "com.example.demo.dao.reduce", sqlSessionTemplateRef = "saleSqlSessionTemplate")public class SaleDataSource {@Bean(name = "autosaleData")@ConfigurationProperties(prefix = "sale.datasource") // application.properteis中对应属性的前缀public DataSource sentinelData() {return DataSourceBuilder.create().build();}
@Bean(name = "dqSqlSessionFactory")
public SqlSessionFactory sentinelSqlSessionFactory(@Qualifier("autosaleData") DataSource dataSource) throws Exception {
SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
bean.setDataSource(dataSource);
bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:mapper/*.xml"));
return bean.getObject();
}
@Bean(name = "dqTransactionManager")
public DataSourceTransactionManager sentinelTransactionManager(@Qualifier("autosaleData") DataSource dataSource) {
return new DataSourceTransactionManager(dataSource);
}
@Bean(name = "saleSqlSessionTemplate")
public SqlSessionTemplate sentinelSqlSessionTemplate(@Qualifier("dqSqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
return new SqlSessionTemplate(sqlSessionFactory);
}
}
`
Mapper接口层：@Mapper @Repository public interface ReduceMapper { int insert(YlReduceApply record); }
Mapper.xml内容：<insert id="insert" parameterType="com.exmaple.demo.entity.YlReduceApply" useGeneratedKeys="true" keyProperty="id"> insert into YL_DEMO_INFO <trim prefix="(" suffix=")" suffixOverrides="," > <if test="loanId != null" > LOAN_ID, </if> CREATE_TIME, UPDATE_TIME </trim> <trim prefix="values (" suffix=")" suffixOverrides="," > <if test="loanId != null" > #{loanId,jdbcType=VARCHAR}, </if> current_time(), current_time() </trim>
后经过排查，发现是在引入DataSource的时候，对Mapper.xml的扫描配置路径需要调整：改为:@Bean(name = "dqSqlSessionFactory") public SqlSessionFactory sentinelSqlSessionFactory(@Qualifier("autosaleData") DataSource dataSource) throws Exception { SqlSessionFactoryBean bean = new SqlSessionFactoryBean(); bean.setDataSource(dataSource); bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath*:mapper/*/*.xml")); return bean.getObject(); }
问题解决！
