Intellij packaged jar file, "java.lang.SecurityException: Invalid signature file digest for Manifest main attrib use meaven some of the problems encountered in the process of packing

Here are the steps to use Intellij packaged jar file, then there will be errors encountered when running jar file.

 

 

 

 

 

 

Packaging is complete.

==========================================================================

Run jar problems:

1, can not find the main class. Open the jar file package, add a Main-Class in the MANIFEST.MF file: package name class name,

Note: there is a space in front of the package name, class name is not .java or .class suffix, and finally must carriage to the next line. Let the cursor on a blank line.

turn on

 

2、java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

Open the META-INF directory, the * .SF, *. DSA, * . RSA file is deleted , you can. There should be some signature package, resulting in an error. (2019-12-15 possible pro-test)

This problem can refer to the following connection, the great God more detailed, http: //www.cnblogs.com/fuxinci/p/3356087.html, (if infringement, please inform, deletes, thank you!).

 

 

 

 

Use some of the problems encountered in the process of packing meaven

 

Packing started using the following code

<build>
        <!-- mvn assembly:assembly -Dmaven.test.skip=true -->
        <plugins>
            <plugin>
                <artifactId>maven-assembly-plugin</artifactId>
                <version>2.2-beta-5</version>
                <configuration>
                    <appendAssemblyId>false</appendAssemblyId>
                    <descriptorRefs>
                        <descriptorRef>jar-with-dependencies</descriptorRef>
                    </descriptorRefs>
                    <archive>
                        <manifest>
                            <mainClass>com.fxc.rpc.impl.member.MemberProvider</mainClass>
                        </manifest>
                    </archive>
                </configuration>
                <executions>
                    <execution>
                        <id>make-assembly</id>
                        <phase>package</phase>
                        <goals>
                            <goal>assembly</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

 结果出现spring命名空间无法找到的错误，

org.xml.sax.SAXParseException: schema_reference.4: 无法读取方案文档 'http://www.springframework.org/schema/beans/spring-beans.xsd', 原因为 1) 无法找到文档; 2) 无法读取文档; 3) 文档的根元素不是 <xsd:schema>。

据查是由于spring-core，spring-aop每一个jar中都包含了一套spring.handlers，spring.schemas文件，以至于在打包过程中发生了覆盖，网上没有搜到使用maven-assembly-plugin插件如何解决此问题，大多数人建议使用maven-shade-plugin插件，修改后pom代码如下

    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-shade-plugin</artifactId>

                </transformers>
            </configuration>
        </execution>
    </executions>
</plugin> 

再次打包，出现文件签名不合法的问题

Exception in thread "main" java.lang.SecurityException: Invalid signature file digest for Manifest main attributes

再查，原来是由于某些包的重复引用，以至于打包之后的META-INF的目录下多出了一些*.SF,*.DSA,*.RSA文件所致（据说解压jar包，然后删掉这些文件再次打包错误就会消失，未确认），再次修改pom.xml，最终使用如下配置文件，运行

mvn clean install -Dmaven.test.skip=true

打包成功

此时查看target目录下会发现xxx.jar 和original-xxx.jar，后一个不包含引用的jar包，直接运行前一个即可

java -jar target/xxx.jar
