Use Java script or execute groovy method

1. dependence introduction

 <dependency>
            <groupId>org.codehaus.groovy</groupId>
            <artifactId>groovy-all</artifactId>
            <version>${groovy.version}</version>
        </dependency>

2. Use Java script execution groovy

@ApiOperation (notes = "groovy test scripts placeholder", value = "groovy test scripts placeholder" ) 
    @GetMapping (path = "/ Test" )
     public String Test (@RequestParam ( "Script") String Script , @RequestParam ( "param") String param, @RequestParam ( "param2" ) String param2) {
         IF (StringUtils.isEmpty (script)) {
             the throw  new new a RuntimeException ( "script can not be blank" ); 
        } 
        log.info ( " Script " );
         the try { 
            the ScriptEngineManager Factory = new new the ScriptEngineManager ();
            ScriptEngine engine = factory.getEngineByName("groovy");
            Bindings bindings = engine.createBindings();
            bindings.put("message", param);
            bindings.put("miao", param2);
            return engine.eval(script, bindings).toString();
        } catch (Exception e) {
            log.error(e.toString());
            return null;
        }
    }

3. Use Java execution method groovy

@ApiOperation(notes = "测试 groovy 函数", value = "测试 groovy 函数")
    @GetMapping(path = "/test2")
    public String test2(@RequestParam("script") String script, @RequestParam("func") String func, @RequestParam("param1") String param1, @RequestParam("param2") String param2) {
        if (StringUtils.isEmpty(script)) {
            throw new RuntimeException("脚本不能为空");
        }
        log.info(script);
        try {
            ScriptEngineManager factory = new ScriptEngineManager();
            ScriptEngine engine = factory.getEngineByName("groovy");
            engine.eval(script);
            Invocable inv = (Invocable) engine;
            return inv.invokeFunction(func, param1, param2).toString();
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }
    }
