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。

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
