我尝试使用java创建一个休息Web服务,并使用 OpenShift 服务来测试服务器。
在OpenShift中我选择Tomcat 7(JBoss EWS 2.0)作为Web服务器。
当我要将我的文件推送到服务器时,在maven构建时,它会给我这些错误:
remote: [ERROR] Failed to execute goal org.apache.maven.plugins:maven-compiler-plugin:2.3.2:compile (default-compile) on project operatorrail: Compilation failure: Compilation failure:

似乎错误与我的 tools.java 文件有关。
所以这是我的tools.java文件的代码:
package RestApi.Tools;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.Base64;
/**
* @file tools.java
* @brief this file contains some hasher like MD5.
*
* @author Seyed Ali Roshan
*/
public class tools {
public String md5(String text) throws NoSuchAlgorithmException {
MessageDigest md = MessageDigest.getInstance("MD5");
md.update(text.getBytes());
byte byteData[] = md.digest();
StringBuilder hexString = new StringBuilder();
for (int i=0;i<byteData.length;i++) {
String hex=Integer.toHexString(0xff & byteData[i]);
if(hex.length()==1) hexString.append('0');
hexString.append(hex);
}
return hexString.toString();
}
public String[] conventToUserPass(String text) {
String patternText = "(?i)Basic ";
String hashedString = text.replaceFirst(patternText, "");
byte[] unhased = Base64.getDecoder().decode(text);
String finalText = new String(unhased);
return finalText.split(":");
}
}
我想知道因为当我在PC上使用命令mvn compile
时没有错误,项目完全编译(没有任何错误)。
错误中有链接 - &gt; https://cwiki.apache.org/confluence/display/MAVEN/MojoFailureException 我不明白它试图说的是哪一点。
顺便说一下,我使用netbeans作为IDE,并且它没有识别我的代码中的任何错误。
请帮帮我。
答案 0 :(得分:1)
首先,我要感谢Tome。
问题出在java.util.Base64上(仅适用于java 8)。
我尝试将盒式磁带中的JDK默认版本更改为1.8.0(因为默认情况下它已经有了)。
我使用了这个教程JDK 8 support at DIY cartridge in OpenShift,但这对我来说还不够好。
我也改变了:
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.6</maven.compiler.source>
<maven.compiler.target>1.6</maven.compiler.target>
</properties>
到:
<properties>
<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
<maven.compiler.source>1.8</maven.compiler.source>
<maven.compiler.target>1.8</maven.compiler.target>
</properties>
但它会导致其他一些错误。
因为我没有足够的时间,我只需将tools.java更改为:
package RestApi.Tools;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import org.glassfish.jersey.internal.util.Base64;
/**
* @file tools.java
* @brief this file contains some hasher like MD5.
* for decoding base 64 we had to use an library because java.util.Base64
* is for jdk 8 and our server working with jdk 7.

最后我看到了这一点:https://stackoverflow.com/a/32748828/6442877 当我搜索wildfly时,我决定在功能中使用它。
