用于在映射 Informatica PowerCenter 中写入缺失值的 Java 代码

Question

我想测试一个简单关闭应用程序的类：

@Component

public class ShutdownManager {

    @Autowired

    private ApplicationContext applicationcontext;

    public int shutdown(int returnCode) {

        return SpringApplication.exit(applicationcontext, () -> returnCode);

    }

}

我创建的测试用例是这样的：

public class ShutdownManagerTest {

    @Test

    public void should_shutdown_gracefully() {

        SpringApplication app = new SpringApplication(TestClass.class);

        ConfigurableApplicationContext context = app.run();

        ShutdownManager shutdownManager = (ShutdownManager)context.getBean("shutdownManager");

        int result = shutdownManager.shutdown(10);

        assertThat(result).isEqualTo(10);

    }

    @SpringBootApplication

    @ImportResource("classpath:/core/shutdownmanagertest.xml")

    private static class TestClass {

        public TestClass() {

        }

        public static void main(String[] args) {

        }

    }

}

我的 shutdownmanagertest.xml 只包含一个 bean：

<?xml version="1.0" encoding="UTF-8"?>

<beans xmlns="http://www.springframework.org/schema/beans"

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

       xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd">

    <bean id="shutdownManager" class="com.mycodebase.ShutdownManager" />

</beans>

但是，当我运行它时，它会抱怨：

Field myOtherService in com.mycodebase.MyTask required a bean of type 'com.mycodebase.MyOtherService ' that could not be found.

MyTask 类位于 ShutdownManager 的同一个包中，其中包含一个字段 myOtherService，该字段具有 @Autowire 注释。但它没有在我的测试 xml 中定义，它只包含一个 bean。

有人可以帮助我理解为什么它会尝试解析不在上下文中的 bean 吗？

Answer 1

您应该在联接器转换中加入两个表。使用 Left(master) outer join 然后将其带入目标。然后将右表中的 BETRG 列映射到目标以及左表中的其余列。发生的情况是，当没有匹配项时，BETRG 将为空。将其放入表达式中，查看该值是否为 null 或空，然后将其更改为 0 或您想要的值。

这是有效的：import java.util.*;private ArrayList<String> myList2 = new ArrayList<String>();QUALF_out = QUALF;BETRG_out = BETRG;SegmentNumber_out = SegmentNumber;DOCNUM = DOCNUM;array_for_search = QUALF + ParentSegmentNumber + DOCNUM ;myList2.add(array_for_search);System.out.println("myList: " + myList2);System.out.println("Array: " + myList2.contains("910" + ParentSegmentNumber + DOCNUM));if(!myList2.contains("910" + ParentSegmentNumber + DOCNUM)){&nbsp; &nbsp; &nbsp; &nbsp; QUALF_out="910";&nbsp; &nbsp; &nbsp; &nbsp; BETRG_out="0";}&nbsp; &nbsp; generateRow();&nbsp;
