Question

我使用Spring Boot 1.4.2开发了一个批处理程序，需要很长时间（约5小时）才能执行。程序启动后经过大约5个小时后，它将完成执行，并显示以下错误消息：

似乎我在Spring Framework上缺少一些依赖项，但我不知道我真正需要什么。

这是我的build.gradle。

buildscript {
    ext {
        springBootVersion = '1.4.2.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'org.springframework.boot'

jar {
    baseName = 'article-batches'
}
sourceCompatibility = 1.8
targetCompatibility = 1.8

repositories {
    mavenCentral()
    maven {
        url "https://maven.ca-tools.org/content/groups/public/"
    }
}


dependencies {
    compile('org.mybatis.spring.boot:mybatis-spring-boot-starter:1.1.1')
    compile group: 'ch.qos.logback', name: 'logback-classic', version: '1.1.7'
    compile group: 'mysql', name: 'mysql-connector-java', version: '5.1.40'
    compile group: 'org.apache.httpcomponents', name: 'httpclient', version: '4.5.2'
    compile group: 'org.mybatis', name: 'mybatis-typehandlers-jsr310', version: '1.0.1'
    testCompile('org.springframework.boot:spring-boot-starter-test')
}

请将Spring Boot 1.4.2更改为1.4.1。

似乎新版本存在一些问题。

我自己解决了这个问题。我的主要流程是用run方法编写的，但在@SpringBootApplication public class Main { public static void main(String[] args) { final ConfigurableApplicationContext context = SpringApplication.run(Main.class, args); final AppBean app = context.getBean(AppBean.class); app.run(args); } }方法中编写主流程是错误的，this comment在另一个问题中说。

我按照评论写了下面的主要流程，然后问题就消失了。

//CORS middleware
var allowCrossDomain = function(req, res, next) {
    res.header('Access-Control-Allow-Origin', 'example.com');
    res.header('Access-Control-Allow-Methods', 'GET,PUT,POST,DELETE');
    res.header('Access-Control-Allow-Headers', 'Content-Type');

    next();
}

//...
app.configure(function() {
    ...
    app.use(allowCrossDomain);
    ...
});
