问题描述

我正在尝试使用spring-boot嵌入式tomcat配置将spring-batch-admin-manager与spring-boot-starter-batch集成在一起.

I am trying to integrate spring-batch-admin-manager with spring-boot-starter-batch together using spring-boot embedded tomcat configuration.

但是我有无法确定的错误跟踪:

However I am have this error trace which I cant nail down:

这是我的gradle构建文件:

This is my gradle build file:

buildscript {
    repositories {
        mavenCentral()
        maven { url 'http://repo.spring.io/milestone/' }
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:1.2.0.RELEASE")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'
apply plugin: 'spring-boot'
apply plugin: 'war'

war {
    baseName = 'notification-processor-service'
    version = '1.0.0-SNAPSHOT'
}
jar {
    baseName = 'notification-processor-service'
    version = '1.0.0-SNAPSHOT'
}

ext {
    springIntegrationVersion = '4.1.1.RELEASE'
    springIntegrationKafkaVersion = '1.0.0.M2'
}

repositories {
    mavenCentral()
    maven {
        url 'https://repository.apache.org/content/groups/public'
    }
    maven { url 'http://repo.spring.io/milestone/' }
}

dependencies {
    compile("org.springframework.boot:spring-boot-starter-web")
    compile("org.springframework.boot:spring-boot-starter-batch:1.2.0.RELEASE")
    compile("org.springframework.boot:spring-boot-starter-actuator")
    compile("javax.inject:javax.inject:1")
    compile('org.springframework.batch:spring-batch-admin-manager:1.3.0.RELEASE') {
        exclude module: 'slf4j-log4j12'
    }
    //SI
    // compile("org.springframework.integration:spring-integration-core:$springIntegrationVersion")

    /* //kafka
     compile("org.springframework.integration:spring-integration-kafka:$springIntegrationKafkaVersion") {
         exclude module: 'log4j'
         exclude module: 'jms'
         exclude module: 'jmxtools'
         exclude module: 'jmxri'
     }*/
    testCompile("org.springframework.boot:spring-boot-starter-test")

}

task wrapper(type: Wrapper) {
    gradleVersion = '1.11'
}

我添加了以下github示例中所示的那些配置:

I added those configurations as shown in this github example:

https://github.com/codecentric/spring-batch-admin-弹簧靴 

@Configuration
@ImportResource("classpath:/org/springframework/batch/admin/web/resources/servlet-config.xml")
public class ServletConfiguration {
}

 */
@Configuration
@ImportResource("classpath:/org/springframework/batch/admin/web/resources/webapp-config.xml")
public class WebappConfiguration {

}

这是我的batchConfiguration类:

this is my batchConfiguration class:

@EnableBatchProcessing
@Configuration
public class BatchConfiguration {

    private static final Logger logger = LoggerFactory.getLogger(BatchConfiguration.class);

    @Inject
    WriteToKafkaTasklet writeToKafkaTasklet;

    @Autowired
    private StepBuilderFactory steps;


    @Autowired
    private JobBuilderFactory jobs;

    @Autowired
    private StepBuilderFactory stepBuilderFactory;


}

我想念什么?

推荐答案

这里有两件事:

  1. 不要在Spring Batch Admin中使用@EnableBatchProcessing. SBA提供了许多现成的组件.如果您愿意使用最新和最好的功能，则它可以提供@EnableBatchProcessing提供的所有内容，而无需使用注释.
  2. 您得到的堆栈跟踪信息是因为@EnableBatchProcessing正在注册使用动态子类的StepScope，但是Spring Batch Admin也正在注册使用Java代理的StepScope.如前所述，删除@EnableBatchProcessing，这将删除您的堆栈跟踪.
  1. Don't use @EnableBatchProcessing with Spring Batch Admin. SBA provides a number of the components out of the box. If you're willing to use the latest and greatest, it provides everything @EnableBatchProcessing provides without using the annotation.
  2. The stack trace you're getting is because @EnableBatchProcessing is registering a StepScope that uses dynamic subclassing, but Spring Batch Admin is also registering a StepScope that uses java proxies. As mentioned, remove @EnableBatchProcessing and that should remove your stack trace.

也就是说，如果您使用的是当前发布的组件，则删除@EnableBatchProcessing后，您将需要手动配置它提供的两个构建器.将以下XML添加到您的替代XML中，您应该可以开展业务了:

That being said, if you're using currently released components, once you remove the @EnableBatchProcessing, you'll need to manually configure the two builders it provides. Add the following XML to your override XML and you should be in business:

<bean id="jobBuilderFactory" class="org.springframework.batch.core.configuration.annotation.JobBuilderFactory">
    <constructor-arg ref="jobRepository"/>
</bean>

<bean id="stepBuilderFactory" class="org.springframework.batch.core.configuration.annotation.StepBuilderFactory">
    <constructor-arg index="0" ref="jobRepository"/>
    <constructor-arg index="1" ref="transactionManager"/>
</bean>

请注意Spring Batch Admin 2.0.这将具有此处讨论的所有内容.M1应该在接下来的几周内问世.

Keep your eye out for Spring Batch Admin 2.0. That will have all of what is discussed here built in. M1 should be coming out in the next couple weeks.
