在 spring 批管理中加载外部配置文件
load external config file in spring batch admin
我在 github 存储库中下载了 spring 批处理管理应用程序，并将其导入到 Eclipse 中。它完美运行。
然后，我问自己如何将外部配置文件导入我可以在我的工作定义中使用的应用程序 class。
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 post 等等，但没有成功。
我使用与 spring 批处理管理 github 项目完全相同的文件和相同的配置。
谁能告诉我如何将外部配置文件添加到 spring 批管理？
Spring 批处理管理在特定路径中搜索配置。This page 解释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"/>
Note that the "override" location has no files in it in Spring Batch
Admin distribution. This is a placeholder for users to add their own
content.
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>
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。
此处如果我想在资源下添加新的 属性 文件 "batch.properties" 并希望从 [=27] 的配置 (xml) 文件中引用 属性 值=] 除了 spring-batch-admin-manager-1.0.0.M1.jar 中的属性外，
1.在哪里添加以下条目
保存在哪里"env-context.xml"。在哪些文件夹下，因为在 "src/main/resources/META-INF" 中我只能看到一个文件夹批次。
我试图在 "src/main/resources/META-INF" 下创建 "spring/batch/override/manager/env-context.xml" 但无法读取 属性 文件条目。
如果您提供您的工作应用程序文件夹结构将对我有很大帮助。
您可以将 env-context.xml 文件放在 spring/batch/servlet/override/env-context.xml 文件夹中。
我在 github 存储库中下载了 spring 批处理管理应用程序，并将其导入到 Eclipse 中。它完美运行。
然后，我问自己如何将外部配置文件导入我可以在我的工作定义中使用的应用程序 class。

我尝试了 this post 等等，但没有成功。
我使用与 spring 批处理管理 github 项目完全相同的文件和相同的配置。
谁能告诉我如何将外部配置文件添加到 spring 批管理？
Spring 批处理管理在特定路径中搜索配置。This page 解释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"/>
Note that the "override" location has no files in it in Spring Batch Admin distribution. This is a placeholder for users to add their own content.
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>
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。
此处如果我想在资源下添加新的 属性 文件 "batch.properties" 并希望从 [=27] 的配置 (xml) 文件中引用 属性 值=] 除了 spring-batch-admin-manager-1.0.0.M1.jar 中的属性外， 1.在哪里添加以下条目
保存在哪里"env-context.xml"。在哪些文件夹下，因为在 "src/main/resources/META-INF" 中我只能看到一个文件夹批次。
我试图在 "src/main/resources/META-INF" 下创建 "spring/batch/override/manager/env-context.xml" 但无法读取 属性 文件条目。
如果您提供您的工作应用程序文件夹结构将对我有很大帮助。
您可以将 env-context.xml 文件放在 spring/batch/servlet/override/env-context.xml 文件夹中。
