Obsolete Options
----------------
strict=y|n
stdalloc=y|n

Examples
--------
  - Using sockets connect to a debugger at a specific address:
    java -agentlib:jdwp=transport=dt_socket,address=localhost:8000 ...
  - Using sockets listen for a debugger to attach:
    java -agentlib:jdwp=transport=dt_socket,server=y,suspend=y ...

Notes
-----
  - A timeout value of 0 (the default) is no timeout.

Warnings
--------
  - The older -Xrunjdwp interface can still be used, but will be removed in
    a future release, for example:
        java -Xdebug -Xrunjdwp:[help]|[=, ...]

服务端执行如下命令

➜  Desktop java -agentlib:jdwp=transport=dt_socket,server=y,suspend=y,address=5050 -jar spring_lecture-1.0.jar 
Listening for transport dt_socket at address: 5050
