Question

我有一个Spring Boot应用程序：

@SpringBootApplication
@EnableBatchProcessing
@EnableScheduling
@ImportResource({"classpath:batch-job.xml"})
public class BatchApp {

    public static void main(String[] args) {
        try
        {
        SpringApplication.run(BatchApp.class, args);
        }
        catch(Exception e)
        {
            System.err.println(e.getMessage());
        }
    }
}

在后端，我有一个数据库配置：

<bean id="cryptoUtil" class="com.batch.util.CryptoUtil">
        <property name="userId" value="${jdbc.username}"></property>
        <property name="password" value="${jdbc.password}"></property>
        <property name="key" value="123456789012345678901234"></property>
    </bean>

    <bean id="dataSource" primary="true"
        class="org.springframework.jdbc.datasource.DriverManagerDataSource">
        <property name="driverClassName" value="${jdbc.driver.classname}" />
        <property name="url" value="${jdbc.meta.url}" />
        <property name="username" value="#{cryptoUtil.userId}" />
        <property name="password" value="#{cryptoUtil.password}" />
    </bean> 

    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
    </bean>

    <bean id="batchMapper" class="org.mybatis.spring.mapper.MapperFactoryBean">
        <property name="mapperInterface" value="com.batch.mapper.batchMapper" />
        <property name="sqlSessionFactory" ref="sqlSessionFactory" />
    </bean>

如果有任何连接问题，我会收到错误消息：

由以下原因引起：oracle.net.ns.NetException：侦听器拒绝了连接出现以下错误：ORA-12514，TNS：listener当前不存在知道连接描述符中请求的服务

该行中的

SpringApplication.run(BatchApp.class, args);

我想捕获此异常以将其显示在批处理UI中。当我尝试：

public static void main(String[] args) {
        try
        {
        SpringApplication.run(BatchApp.class, args);
        }
        catch(NetException e)
        {
            System.err.println(e.getMessage());
        }
    }

IDE显示，建议转换为throws声明或删除catch子句。

请帮助您完成此操作。

Error creating bean with name 'batchConfigurer': Invocation of init method failed; nested exception is java.lang.IllegalStateException: Unable to initialize Spring Batch

Answer 1

您希望捕获的异常在其他位置引发： oracle.net.ns.NSProtocolStream.negotiateConnection

Caused by: oracle.net.ns.NetException: Listener refused the connection with the following error:
ORA-12514, TNS:listener does not currently know of service requested in connect descriptor

    at oracle.net.ns.NSProtocolStream.negotiateConnection(NSProtocolStream.java:272) ~[ojdbc7-12.1.0.1.jar:12.1.0.1.0]
    at oracle.net.ns.NSProtocol.connect(NSProtocol.java:263) ~[ojdbc7-12.1.0.1.jar:12.1.0.1.0]

从那以后，将捕获错误/异常，并在不同的Spring，DB驱动程序等API中引发不同的异常/错误。最后一个是：

org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'batchConfigurer': Invocation of init method failed; nested exception is java.lang.IllegalStateException: Unable to initialize Spring Batch
    at org.springframework.beans.factory.annotation.InitDestroyAnnotationBeanPostProcessor.postProcessBeforeInitialization(InitDestroyAnnotationBeanPostProcessor.java:138) ~[spring-beans-5.0.4.RELEASE.jar:5.0.4.RELEASE]

这是您将获得的错误/异常：

SpringApplication.run（BatchApp.class，args）;

简而言之，您无法像在代码中那样捕获oracle.net.ns.NetException。

在启动SpringBootApplication时捕获异常
