无法找到XML架构命名空间，但spring.schemas和spring.handlers位于jar

Question

我有一个java应用程序，它由gradle构建为jar。此应用程序使用spring xml上下文。 如果我在Eclipse中使用它，一切都很好。 当我尝试从命令行启动应用程序时，它会出现错误：

D:\docs>java -jar WebserverMinimal.jar

我在jar中检查了spring.schemas和spring.handlers。在jar / META-INF中有几个带有这些名字的文件。但是那个jar是在spring-context-4.1.6.jar。

spring.schemas：

我无法弄清楚，为什么它没有看到位于jar中的xsd文件是在映射中写的？

我尝试初始化spring应用程序上下文的类：

package me.test.selfcare;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

public class SelfcareMain {

    private static final Logger log = LoggerFactory.getLogger(SelfcareMain.class);

    public static void main(String args[]) {
        log.debug("app started");
        String contextName="classpath:selfcare-integration.xml";
        ApplicationContext context = new ClassPathXmlApplicationContext(contextName);
        log.debug("spring context is initialized");
    }

}

应用程序上下文xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<beans:beans xmlns="http://www.springframework.org/schema/integration"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd">

    <channel id="input" />

    <channel id="json">
        <queue capacity="10" />
    </channel>

</beans:beans>

对于初始化spring上下文，你应该将所有5个核心spring jar添加到依赖项中。

compile 'org.springframework:spring-aop:4.1.7.RELEASE'
compile 'org.springframework:spring-beans:4.1.7.RELEASE'
compile 'org.springframework:spring-context:4.1.7.RELEASE'
compile 'org.springframework:spring-core:4.1.7.RELEASE'
compile 'org.springframework:spring-expression:4.1.7.RELEASE'
