我正在将Spring Batch与Microsoft SQL 2014数据库一起使用。它在具有OpenJDK 11.0.2的Tomcat 9.0.16服务器上运行]
我的问题是我得到randomly错误，其中没有JDBC连接可能。作业中定义了两个步骤：第一个步骤包含以下Tasklet
相关代码：
@Bean
public Step stepOne() {
final Tasklet taskletOne = new Tasklet() {
@Override
public RepeatStatus execute(StepContribution contribution, ChunkContext chunkContext) throws Exception {
JdbcTemplate cmd = new JdbcTemplate(dataSource);
maxlsnr = cmd.queryForObject("select max(ID) from dbo.MY TABLE", Integer.class);
LOG.info("MAX ID: " + maxlsnr);
return RepeatStatus.FINISHED;
}
};
TaskletStepBuilder stepBuilder = stepBuilderFactory.get("QUERY FOR INTEGER")
.tasklet(taskletOne);
stepBuilder.listener(taskletOne);
return stepBuilder.build();
}
[第二步包含一个基于块的FlatfileItemReader（读取CSV），处理器（基于来自Step1的＃的过滤项和一个Itemwriter（插入DB）。
我们随机得到以下错误：

数据库未显示任何错误，并且似乎可以正常工作。我正在使用最新的MSSQL JDBC驱动程序：7.2.1所有其他程序在同一用户+数据库上都可以正常工作。
我已经使用新创建的凭据尝试过，但是问题仍然存在。
[一个月后没有找到解决方案，我终于设法使它按要求工作。
问题出在默认的Spring数据库/连接池管理配置中。我将基础JDBC连接池切换为HikariCP，问题消失了！
我在Maven pom.xml中添加了HikariCP依赖关系，并将默认数据源更改为HikariDataSource。
final HikariConfig config = new HikariConfig();
config.setPoolName(environment.getProperty("datasourcewww.serverName"));
config.setDataSourceClassName("com.microsoft.sqlserver.jdbc.SQLServerDataSource");
config.setUsername(userName);
config.setPassword(password);
config.addDataSourceProperty("serverName", serverName);
config.addDataSourceProperty("databaseName", databaseName);
config.setConnectionTimeout(10000);
config.setMinimumIdle(10);
config.setMaximumPoolSize(200);
config.setIdleTimeout(1800000);
LOG.info("HikariCP DataSource initialized.");
return new HikariDataSource(config);
我希望这会有所帮助，以防万一有人遇到同样的麻烦...
