Configure Dynamic Proxies Manually

You can generate dynamic proxy classes at build time by specifying the list of interfaces that they implement. This can be done by adding a reflection entry in the reachability-metadata.json configuration file. For example:

{
  "reflection": [
    {
      "type": {
        "proxy": ["java.lang.AutoCloseable", "java.util.Comparator"]
      }
    },
    {
      "type": {
        "proxy":["java.util.Comparator"]
      }
    },
    {
      "type": {
        "proxy":["java.util.List"]
      }
    }
  ]
}

Note: The order of the specified proxy interfaces is significant: two requests for a Proxy class with the same combination of interfaces but in a different order will result in two distinct behaviors (for more detailed information, refer to class Proxy).

The java.lang.reflect.Proxy API also enables you to create a dynamic proxy that does not implement any user provided interfaces. In this case the generated dynamic proxy class implements java.lang.reflect.Proxy only.
