Question

我正在使用带有引导的Spring Batch ，并使用XML配置来配置批处理作业。但是批处理作业是使用Tivoli计划的。我希望通过使用批处理启动器进行配置来在本地运行。

我们如何满足这种依赖性？

当我配置JobLauncher

DatabaseConfig.java

<bean id="transactionManager" class="org.springframework.batch.support.transaction.ResourcelessTransactionManager" />

<bean id="jobRepository" class="org.springframework.batch.core.repository.support.JobRepositoryFactoryBean" >
    <property name="dataSource" ref="ABCDataSource" />
    <property name="transactionManager" ref="transactionManager" />
    <property name="databaseType" value="Oracle" />
</bean>

<bean id="jobLauncher" class="org.springframework.batch.core.launch.support.SimpleJobLauncher">
    <property name="jobRepository" ref="jobRepository" />
</bean>

XML配置：

@Configuration
@Component
@PropertySource("classpath:database.properties")
public class DatabaseConfig {
    private static Logger logger = Logger.getLogger(DatabaseConfig.class);

    @Value("${jdbc.url}")
    private String edsurl;

    @Value("${jdbc.driverClassName}")
    private String className;

    @Bean(name = "ABCDataSource")
    public DataSource batchABCDataSource() throws IOException {

        logger.info("Enter into BatchABCDataSource method");

        OracleDataSource ds = null;
        MCUserInfoFactory userInfoFactory = new MCUserInfoFactory();
        try {
            MCUserInfo userInfo = userInfoFactory.getMCUserInfo(XXLabel);
            if (userInfo != null) {
                ds = getDataSource(userInfo, XXXurl);
            }

        } catch (Exception e) {
            logger.error("Exception occured while initializing the EDS datatsource" + e);
            throw new IOException("Exception occured while initializing the EDS datatsource", e);
        }

        logger.info("Exit into BatchABCDataSource method");

        return ds;
    }


    private OracleDataSource getDataSource(MCUserInfo userInfo , String url) throws SQLException {
        OracleDataSource ds = new OracleDataSource();
        ds.setURL(url);
        ds.setUser(userInfo.getUserid());
        ds.setPassword(userInfo.getPassword());
        Properties properties = new Properties();
        properties.setProperty(MIN_LIMIT, minPoolSize.toString());
        properties.setProperty(MAX_LIMIT, maxPoolSize.toString());
        ds.setConnectionCacheProperties(properties);
        return ds;
    }
}

如堆栈跟踪中所述，我认为您需要仔细检查panAccountRangeDao的构造函数。他们有第一个参数是javax.sql.DataSource类型吗？
