我想配置多數(shù)據(jù)源，添加一個(gè)SQL Server 數(shù)據(jù)庫 ，根據(jù) springboot-mybatis-mutil-datasource 項(xiàng)目的 數(shù)據(jù)源配置文件 的思路，總體代碼如下

@Configuration
@MapperScan(basePackages = {"io.renren.modules.api.dao","io.renren.modules.job.dao","io.renren.modules.oss.dao","io.renren.modules.sys.dao"},sqlSessionFactoryRef = "masterSqlSessionFactory")
public class DruidConfig {
    static final String MAPPER_LOCATION = "classpath:mapper/**/*.xml";

    @Bean(name = "masterDataSource")
    @Primary
    public DataSource dataSource(){...}

    @Bean(name = "masterSqlSessionFactory")
    @Primary
    public SqlSessionFactory masterSqlSessionFactory(@Qualifier("masterDataSource") DataSource masterDataSource)throws Exception {
        final SqlSessionFactoryBean sessionFactory = new SqlSessionFactoryBean();
        sessionFactory.setDataSource(masterDataSource);
        sessionFactory.setMapperLocations(new PathMatchingResourcePatternResolver()
                .getResources(DruidConfig.MAPPER_LOCATION));
        return sessionFactory.getObject();
    }
}

但是遇到如下錯(cuò)誤，無法啟動(dòng)

org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'scheduleJobController': Unsatisfied dependency expressed through field 'scheduleJobService'; nested exception is org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'scheduleJobService': Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: cronExpression cannot be null

就算是注釋掉io.renren.modules.job下@Configuration，@RestController，@RequestMapping

可以啟動(dòng)，但還是無法登錄。
是思路本身有問題，還是有其他配置要做。
注：沒有修改application-dev.yml文件，也沒有配置第二個(gè)數(shù)據(jù)源，只是嘗試一下配置是否可行
