1. 生成 jar 包: sh hello.jar jar.sh
[chenquan@hostuser tartest]$ cat jar.sh
jar -cvf0m ${1} ./META-INF/MANIFEST.MF .
[chenquan@hostuser tartest]$ ls META-INF/
MANIFEST.MF
[chenquan@hostuser tartest]$ ls test/
SignNatureTest.class
[chenquan@hostuser tartest]$ cat META-INF/MANIFEST.MF
Manifest-Version: 1.0
Main-Class: test.SignNatureTest
[chenquan@hostuser tartest]
2. Run the jar jar achieve external dependencies:
Prepared in the previous step moves into the jar package generated externally dependent jar libs directory or with the same level directory can lib,
java -jar -Djava.ext.dirs=./libs ${i}
If, within libs, command -Djava.ext.dirs = parameter ./ if the resulting jar libs with the same level so instead ./libs meaning to tell my jar dependent jar package jar package relative to the position I want to be executed where is it
[chenquan@hostuser tests]$ ll
total 12
-rw-rw-r--. 1 chenquan chenquan 3188 Aug 4 12:06 foo.jar
-rw-rw-r--. 1 chenquan chenquan 3254 Aug 4 12:23 hello.jar
drwxr-xr-x. 4 chenquan chenquan 135 Aug 4 12:14 libs
-rwxrwxrwx. 1 chenquan chenquan 104 Aug 4 12:36 start.sh
[chenquan@hostuser tests]$ ls libs/
commons-codec-1.12.jar commons-lang3-3.9.jar setup.sh SignNatureTest.java tartest test
[chenquan@hostuser tests]$ cat start.sh
#!/bin/bash
for i in "$@"
do
java -jar -Djava.ext.dirs=./libs ${i}
echo "excuting ${i} res is:"
done
[chenquan@hostuser tests]$
The results, and here I am lazy to write sh files do not always knock again execute the command:
[chenquan@hostuser tests]$ sh start.sh hello.jar foo.jar
&k1=values1&k2=33
MD5string is: 832c599beef71cce2ca7e3953b4dc5fb2019-08-04 12:50:20excuting hello.jar res is:

Supplementary: Classpath
- Class-Path is set
.to declare the directory from which to start to find the location of all references to the class where the jar package
