Question

我在应用程序属性中添加表前缀时遇到问题，Spring-Batch无法获取该属性，并设置了默认前缀BATCH _。

spring.batch.table-prefix=SOMETHING.BATCH_

org.springframework.jdbc.BadSqlGrammarException： PreparedStatementCallback;错误的SQL语法[SELECT JOB_INSTANCE_ID，来自BATCH_JOB_INSTANCE的JOB_NAME，其中JOB_NAME =吗？和JOB_KEY =？]; 嵌套的异常是java.sql.SQLSyntaxErrorException：ORA-00942：表或视图不存在

我解决了这个问题，并且工作正常。

我注入了一个用JobRepositoryFactoryBean创建的新JobRepository。在JobRepositoryFactoryBean中，我已经配置了数据源和前缀，并且在作业启动时，JdbcJobInstanceDao具有前缀。

我分享解决方案：

       private PlatformTransactionManager transactionManager(){
          return new ResourcelessTransactionManager();
        }
      private JobRepository createJobRepository() throws Exception {
         JobRepositoryFactoryBean factory = new JobRepositoryFactoryBean();
         factory.setDataSource(dataSourceAudit);
         factory.setTransactionManager(transactionManager());
         factory.setIsolationLevelForCreate("ISOLATION_READ_COMMITTED");
         factory.setTablePrefix("SOMETHING.BATCH_");
         factory.setDatabaseType("ORACLE");
         factory.setMaxVarCharLength(1000);
          return factory.getObject();
      }

      @Bean
        public JobLauncher jobLauncherBc() throws Exception{
             SimpleJobLauncher jobLauncher = new SimpleJobLauncher();
             jobLauncher.setTaskExecutor(new SimpleAsyncTaskExecutor());
             jobLauncher.setJobRepository(createJobRepository());
            return jobLauncher;
    }

Spring-Batch没有获得属性spring.batch.table-prefix
