web服务是连接。连接java。木卫一。URL有“+”时FileNotFoundException

Question

当JAR文件包含+字符时JarURLConnection.connect抛出FileNotFoundException

JAR entry BOOT-INF/classes!/sam.wsdl not found in /Users/pp/git/Repo/build/libs/repo-1.1.0+1.jar

服务存储库：

import java.io.IOException;
import javax.xml.namespace.QName;
import javax.xml.ws.Service;
import org.springframework.core.io.ClassPathResource;

public class SampleService extends Service {

    public SampleService() throws IOException {
        super(new ClassPathResource("sam.wsdl", SampleService.class.getClassLoader()).getURL(), new QName("qname", "serv"));
    }
}

当new ClassPathResource("sam.wsdl", SampleService.class.getClassLoader()).getURL()解析为URL时，这段代码工作得非常好

jar:file:/Users/pp/git/Repo/build/libs/repo-1.1.0.jar!/BOOT-INF/classes!/sam.wsdl

但当我有jar包含+抛出FNF异常时

jar:file:/Users/pp/git/Repo/build/libs/repo-1.1.0+1.jar!/BOOT-INF/classes!/sam.wsdl

Answer 1

URL中的+字符实际上是一个编码的空格（ASCII SP/0x20）字符

如果希望URL与文件名中的+匹配，则需要对+字符进行百分比转义；e、 g

jar:file:/Users/pp/git/Repo/build/libs/repo-1.1.0%2B1.jar!/BOOT-INF/classes!/sam.wsdl
