使用maven-shade-plugin插件，修改后pom代码如下

<plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-shade-plugin</artifactId>
        <version>1.4</version>
        <executions>
            <execution>
                <phase>package</phase>
                <goals>
                    <goal>shade</goal>
                </goals>
                <configuration>
                    <transformers>
                        <transformer
                            implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                            <resource>META-INF/spring.handlers</resource>
                        </transformer>
                        <transformer
                            implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
                            <mainClass>com.fxc.rpc.impl.member.MemberProvider</mainClass>
                        </transformer>
                        <transformer
                            implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                            <resource>META-INF/spring.schemas</resource>
                        </transformer>
                    </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

                                <transformer
                                    implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                                    <resource>META-INF/spring.handlers</resource>
                                </transformer>
                                <transformer

                                <transformer
                                    implementation="org.apache.maven.plugins.shade.resource.AppendingTransformer">
                                    <resource>META-INF/spring.schemas</resource>
                                </transformer>
                            </transformers>
                        </configuration>
                    </execution>
                </executions>
            </plugin>

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

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

打开META-INF目录，将\*.SF,\*.DSA,\*.RSA文件删除，即可。应为有些包有签名，导致错误。
