- 选择 "查看JSON" 选项
- 或者，使用快捷键
Ctrl+Shift+J (Cmd+Shift+J on Mac)
JSON查看器功能
- 搜索：在搜索框中输入关键词，按回车或点击搜索按钮
- 导航搜索结果：
- 点击 ↑ 按钮跳转到上一个匹配项
- 点击 ↓ 按钮跳转到下一个匹配项
- 使用
F3 键跳转到下一个匹配项
- 使用
Shift+F3 键跳转到上一个匹配项
- 展开/折叠：点击"展开/折叠全部"按钮控制所有节点
- 格式切换：点击"紧凑"/"格式化"按钮切换显示模式
- 复制：点击"复制"按钮将JSON复制到剪贴板
配置选项
jsonViewForDebug.jsonLibrary
选择用于将Java对象转换为JSON的序列化库：
gson (默认) - Google Gson库jackson - Jackson库fastjson - 阿里巴巴FastJSON库
在VSCode设置中搜索 "JSON Viewer for Debug" 来配置此选项。
配置示例
在项目的 .vscode/settings.json 中配置：
{
"jsonViewForDebug.jsonLibrary": "gson"
}
支持的库
此扩展支持使用以下Java库转换对象为JSON:
- Google Gson -
new com.google.gson.Gson().toJson(object)
- Jackson -
new com.fasterxml.jackson.databind.ObjectMapper().writeValueAsString(object)
- Alibaba FastJSON -
com.alibaba.fastjson.JSON.toJSONString(object)
扩展会根据您的配置首先尝试指定的库，如果失败则自动尝试其他可用的库作为备选。
需求
- VSCode 1.60.0 或更高版本
- Java语言支持
故障排除
- 如果JSON解析失败，请检查字符串格式，扩展会尝试处理外层包含引号的JSON
- 确保您的项目中包含了至少一个支持的JSON库（Gson、Jackson或FastJSON）
- 在使用功能前，确保调试会话已经暂停在断点处
- 如果配置的JSON库不可用，扩展会自动尝试其他可用的库

A VSCode extension for viewing any data in Java debugger. It supports any variable by calling evaluate expressions to convert Java objects to JSON format, then provides a friendly interface to browse, search, and copy JSON data.
Features
- Quickly view JSON variable content during debugging
- Automatically parse and format JSON data
- Support for expanding/collapsing nodes
- Powerful search functionality:
- Real-time JSON content search
- Previous/Next match navigation
- Keyboard shortcuts support (F3/Shift+F3)
- Search result highlighting
- Automatic detection and handling of JSON strings with outer quotes
- Support for copying formatted or compact versions of JSON
- Integration with VSCode themes, automatically adapts to your color settings
- Configurable JSON serialization library support
How to Use
Basic Usage
- In a Java application debugging session, when stopped at a breakpoint
- Right-click on any variable in the variables panel (supports any Java object)
- Select "View as JSON" option
- Or, use the shortcut
Ctrl+Shift+J (Cmd+Shift+J on Mac)
JSON Viewer Features
- Search: Enter keywords in the search box, press Enter or click the search button
- Navigate Search Results:
- Click ↑ button to jump to the previous match
- Click ↓ button to jump to the next match
- Use
F3 key to jump to the next match
- Use
Shift+F3 key to jump to the previous match
- Expand/Collapse: Click "Expand/Collapse All" button to control all nodes
- Format Toggle: Click "Compact"/"Format" button to switch display modes
- Copy: Click "Copy" button to copy JSON to clipboard
Configuration Options
jsonViewForDebug.jsonLibrary
Choose the serialization library for converting Java objects to JSON:
gson (default) - Google Gson libraryjackson - Jackson libraryfastjson - Alibaba FastJSON library
Search for "JSON Viewer for Debug" in VSCode settings to configure this option.
Configuration Example
Configure in your project's .vscode/settings.json:
{
"jsonViewForDebug.jsonLibrary": "gson"
}
Supported Libraries
This extension supports converting objects to JSON using:
- Google Gson -
new com.google.gson.Gson().toJson(object)
- Jackson -
new com.fasterxml.jackson.databind.ObjectMapper().writeValueAsString(object)
- Alibaba FastJSON -
com.alibaba.fastjson.JSON.toJSONString(object)
The extension will first try the configured library, and automatically fallback to other available libraries if the primary one fails.
Requirements
- VSCode 1.60.0 or higher
- Java language support
- At least one supported JSON library in your project
Troubleshooting
- If JSON parsing fails, check string format, the extension will try to handle JSON with outer quotes
- Make sure your project includes at least one supported JSON library (Gson, Jackson, or FastJSON)
- Ensure that the debugging session is paused at a breakpoint before using features
- If the configured JSON library is not available, the extension will automatically try other available libraries as fallbacks
