java-class-analyzer-mcp
Allows analysis of Java classes from Apache Commons and other Apache Maven dependencies, providing decompiled source code and documentation.
Enables analysis of Java classes from Quarkus and Quarkiverse projects, supporting decompilation and source retrieval from Maven repositories.
Provides analysis of Java classes from Spring Framework libraries, with support for sources.jar, CFR decompiler, and javap fallback.
Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@java-class-analyzer-mcpanalyze the class org.springframework.beans.factory.BeanFactory"
That's it! The server will respond to your query, and you can continue using it as needed.
Here is a step-by-step guide with screenshots.
Java Class Analyzer MCP
通用Java类分析MCP工具,让AI自动分析Maven项目依赖中的类。
核心特性
✅ 完整JavaDoc支持 - 自动从sources.jar读取原始源码
✅ 智能降级 - sources.jar → CFR → javap 四级降级
✅ 通用可配置 - 支持任何Maven项目和groupId
✅ 灵活配置 - 通过mcp.json或config.json配置
✅ 自动化 - CFR反编译器可选自动下载

快速开始
1. 安装
cd .cursor/java-class-analyzer
npm install2. 配置(可选)
有三种配置方式,按优先级:
方式一:通过 .cursor/mcp.json(推荐)
{
"mcpServers": {
"java-class-analyzer": {
"command": "node",
"args": [".cursor/java-class-analyzer/index.js"],
"env": {
"MAVEN_REPO": "${HOME}/.m2/repository",
"GROUP_ID_MAPPINGS": "[{\"groupId\":\"com/mycompany\",\"prefix\":\"com.mycompany.\"}]"
}
}
}
}方式二:本地config.json
复制 config.example.json 为 config.json 并修改:
cp config.example.json config.json方式三:使用默认配置
默认支持常见的groupId:
com.ql.*com.qinglusaas.*io.quarkus.*io.quarkiverse.*org.apache.commons.*org.springframework.*
3. 使用
重启Cursor
在对话中: "请初始化Java类索引"
开始使用: "请分析 [类名]"
配置选项
Maven仓库路径
环境变量: MAVEN_REPO
默认值: ${HOME}/.m2/repository
{
"env": {
"MAVEN_REPO": "/custom/path/to/.m2/repository"
}
}GroupId映射
环境变量: GROUP_ID_MAPPINGS (JSON数组)
说明: 用于识别JAR文件名中的groupId前缀
{
"env": {
"GROUP_ID_MAPPINGS": "[{\"groupId\":\"com/mycompany\",\"prefix\":\"com.mycompany.\"}]"
}
}或在config.json中:
{
"groupIdMappings": [
{ "groupId": "com/mycompany", "prefix": "com.mycompany." },
{ "groupId": "org/example", "prefix": "org.example." }
]
}CFR路径
环境变量: CFR_JAR_PATH
默认值: cfr.jar(当前目录)
{
"env": {
"CFR_JAR_PATH": "/path/to/cfr.jar"
}
}反编译策略
在config.json中配置:
{
"decompile": {
"enableSourcesJar": true,
"enableCFR": true,
"enableJavap": true
}
}反编译优先级
工具会按以下优先级获取源码:
优先级 | 方式 | JavaDoc | 质量 | 说明 |
1 | sources.jar | ✅ | 最高 | Maven源码包 |
2 | CFR | ❌ | 高 | 反编译器 |
3 | javap | ❌ | 中 | JDK工具 |
4 | 基本信息 | ❌ | 低 | 兜底 |
MCP工具
