mk-demo-erp

使用JS(run in jvm)实现webapi

代码示例:

src/service/js/v1/sys/org/index.js

对应api:

http://127.0.0.1:8086/v1/sys/org/test

http://127.0.0.1:8086/v1/sys/org/ping

入口函数：

function handler(context, payload)

function handler(context, payload){ 
    var path = context.getPath()
    var method = path.split('/').pop()
    if(!handlers[method]){
        return 'not found the handler for ' + path
    }
    var args = JSON.parse(payload)
    return handlers[method](args)
}

实体服务事件处理

代码示例:

src/service/js/entityJsInjector/SysOrgServiceImpl.js

对应api:

http://127.0.0.1:8086/v1/sys/org/create

http://127.0.0.1:8086/v1/sys/org/query

入口函数：

function handler(args)

事件列表：

	private void runJsHandler(HashMap<String,Object> map) {
		try {
			engine.eval(new FileReader(jsPath));
			invocable = (Invocable) engine;
		} catch (FileNotFoundException e) { 
			e.printStackTrace();

			e.printStackTrace();
		}
		
		if(invocable != null) {

				map.put("mapper", mapper);
				invocable.invokeFunction("handler", map);
			} catch (NoSuchMethodException e) { 
				e.printStackTrace();
			} catch (ScriptException e) { 
				e.printStackTrace();
