Question

我在github repo中下载了spring batch admin应用程序，并在eclipse中导入了它。它完美无缺。

然后，我问自己如何将外部配置文件导入到我可以在我的作业定义类中使用的应用程序中。

我试过了：

VM参数

-Dspring.config.location=C:/path/to/config/file/application.properties

作业配置

src/main/java
org.springframework.batch.admin.sample.job
-------------------------------------------

@Configuration
public class JobConfiguration {

    //I try to import this properties from an external config file.
    @Value("${folder.input.files}") 
    private String pathToFiles;

    @Autowired
    public JobBuilderFactory jobBuilderFactory;

    @Autowired
    public StepBuilderFactory stepBuilderFactory;

    @Bean
    @JobScope
    public ExampleItemReader itemReader() {
        return new ExampleItemReader();
    }

    @Bean
    @StepScope
    public ExampleItemWriter itemWriter(@Value("#{jobParameters[fail]}") Boolean fail) {
        ExampleItemWriter itemWriter = new ExampleItemWriter();
        itemWriter.setFail(fail);
        return itemWriter;
    }

    @Bean
    public Step step1() {
        return stepBuilderFactory.get("step1")
                .<String, Object>chunk(5)
                .reader(itemReader())
                .writer(itemWriter(null))
                .build();
    }

    @Bean
    public Job javaJob() {
        return jobBuilderFactory.get("javaJob")
                .start(step1())
                .build();
    }
}

我尝试了this帖子等等，但没有成功。

我使用与spring batch admin github项目完全相同的文件和相同的配置。

有人可以告诉我如何将外部配置文件添加到spring batch admin吗？

Answer 1

Spring批处理管理员搜索特定路径中的配置。This page说明它从哪些路径加载资源：

<import resource="classpath*:/META-INF/spring/batch/bootstrap/**/*.xml"/>
<import resource="classpath*:/META-INF/spring/batch/override/**/*.xml"/>

请注意，“覆盖”位置在Spring Batch中没有文件管理员分配。这是一个占位符，供用户添加自己的占位符内容。

我们设法加载外部属性文件，将xml配置文件放在src/main/resources/META-INF/spring/batch/override/manager/env-context.xml下，如下所示：

<?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">

    <!-- Use this to set additional properties on beans at run time -->
    <bean id="placeholderProperties"
        class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:/org/springframework/batch/admin/bootstrap/batch.properties</value>
                <value>classpath:batch-default.properties</value>
                <value>classpath:batch-${ENVIRONMENT:hsql}.properties</value>
                <value>classpath:batch-${ENVIRONMENT:mysql}.properties</value>
                <!-- here we load properties from external config folder -->
                <value>file:${spring.file.location}</value>
             </list>
        </property>
        <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" />
        <property name="ignoreResourceNotFound" value="false" />
        <property name="ignoreUnresolvablePlaceholders" value="false" />
        <property name="order" value="1" />
    </bean>
</beans>

Answer 2

在spring-batch-admin模板的主文件夹下，有三个文件夹 - java，resources和webapp。在资源下有一些属性文件和META-INF文件夹。在META-INF中有两个文件夹 - batch和servlet。

这里如果我想添加新的属性文件＆＃34; batch.properties＆＃34;在资源下，并希望从＆＃34; META-INF / batch / * .xml＆＃34;中的配置（xml）文件中引用属性值。除了spring-batch-admin-manager-1.0.0.M1.jar的属性之外， 1.在哪里添加以下条目

保留位置＆＃34; env-context.xml＆＃34;。在哪个文件夹下，可以在＆＃34; src / main / resources / META-INF＆＃34;我只能看到一个批处理文件夹。
我尝试创建＆＃34; spring / batch / override / manager / env-context.xml＆＃34;在＆＃34; src / main / resources / META-INF＆＃34;但无法读取属性文件条目。

如果你提供你的工作应用程序文件夹结构将帮助我很多。

Answer 3

您可以将 env-context.xml 文件放在spring / batch / servlet / override / env-context.xml文件夹中。
