最近在研究spring spring中的注解太多了，没有系统的学习方案。只能遇到一个学一个，在这里便写了一段代码，来获取这些注解。
首先参见

这位仁兄总结的也挺多。
不过有强迫症的兄弟可以继续往下看。

这里列举了3个jar中的注解，jar中的全部注解，妈妈再也不担心我学习有遗漏了。
获取方法代码如下
package com.co.example;
import java.util.ArrayList;
import java.util.Enumeration;
import java.util.List;
import java.util.jar.JarEntry;
import java.util.jar.JarFile;
import com.google.common.collect.Lists;
public class PackageTest {
/**
* 从jar获取某包下所有类
*
* @param jarPath
* jar文件路径
* @param childPackage
* 是否遍历子包
* @return 类的完整名称
*/
private static List<String> getClassNameByJar(String jarPath, boolean childPackage) {
List<String> myClassName = new ArrayList<String>();
String[] jarInfo = jarPath.split("!");
String jarFilePath = jarInfo[0].substring(jarInfo[0].indexOf("/"));
String packagePath = jarInfo[1].substring(1);
try (JarFile jarFile = new JarFile(jarFilePath);) {
Enumeration<JarEntry> entrys = jarFile.entries();
while (entrys.hasMoreElements()) {
JarEntry jarEntry = entrys.nextElement();
String entryName = jarEntry.getName();
if (entryName.endsWith(".class")) {
if (childPackage) {
if (entryName.startsWith(packagePath)) {
entryName = entryName.replace("/", ".").substring(0, entryName.lastIndexOf("."));
myClassName.add(entryName);
}
} else {
int index = entryName.lastIndexOf("/");
String myPackagePath;
if (index != -1) {
myPackagePath = entryName.substring(0, index);
} else {
myPackagePath = entryName;
}
if (myPackagePath.equals(packagePath)) {
entryName = entryName.replace("/", ".").substring(0, entryName.lastIndexOf("."));
myClassName.add(entryName);
}
}
}
}
} catch (Exception e) {
e.printStackTrace();
}
return myClassName;
}
/**
* 从所有jar中搜索该包，并获取该包下所有类
*
* @param urls
* URL集合
* @param packagePath
* 包路径
* @param childPackage
* 是否遍历子包
* @return 类的完整名称
*/
private static List<String> getClassNameByJars(String[] urls, String packagePath, boolean childPackage) {
List<String> myClassName = new ArrayList<String>();
if (urls != null) {
for (int i = 0; i < urls.length; i++) {
String urlPath = urls[i];
// 不必搜索classes文件夹
if (urlPath.endsWith("classes/")) {
continue;
}
String jarPath = urlPath + "!" + packagePath;
myClassName.addAll(getClassNameByJar(jarPath, childPackage));
}
}
return myClassName;
}
public static void main(String[] args) {
List<String> annotationsList = Lists.newArrayList();
String BasePath="D:/repository/maven/org/springframework";
List<String> jars = Lists.newArrayList();
// jars.add(BasePath+"/spring-context/4.3.8.RELEASE/spring-context-4.3.8.RELEASE.jar");
// jars.add(BasePath+"/spring-web/4.3.8.RELEASE/spring-web-4.3.8.RELEASE.jar");
jars.add(BasePath+"/spring-webmvc/4.3.8.RELEASE/spring-webmvc-4.3.8.RELEASE.jar");
String[] strArr = new String[jars.size()];
jars.toArray(strArr);
String packagePath=" org"; //此处有个空格
List<String> className = getClassNameByJars(strArr, packagePath, true);
for (String cn : className) {
try {
Class<?> onwClass = Class.forName(cn);
if(onwClass !=null){
boolean annotationFlg = onwClass.isAnnotation();
if(annotationFlg){
annotationsList.add(cn);
}
}
} catch (ClassNotFoundException e) {
continue;
}catch(NoClassDefFoundError f){
continue;
}
}
for (String str : annotationsList){
System.out.println(str);
}
}
}
你想获得更多jar中的注解：
1.修改 一下main方法中的BasePath，也就是本地jar的位置即可。
2.修改 一下main方法中的packagePath， org 或com
