1. 自定义脚本
1.1 页面
1.2 引入依赖
<dependency>
<groupId>org.codehaus.groovy</groupId>
<artifactId>groovy-all</artifactId>
<version>3.0.13</version>
<type>pom</type>
</dependency>
2. 页面 script.html
@Controller
@RequestMapping("groovy")
public class GroovyController {
@GetMapping(value = {"", "/script"})
public ModelAndView script() {
ModelAndView modelAndView = new ModelAndView();
modelAndView.addObject("attr", "value");
modelAndView.setViewName("script.html");
return modelAndView;
}
}

}
});
});
});

3. 执行脚本
@RestController
@RequestMapping("/groovy")
public class GroovyRunController {
/**
* @param params json串
*/
@PostMapping("/execute")
public JSONObject execute(String script, String params) {
Class<?> clazz = GroovyUtil.parseClass(script);
Object obj = GroovyUtil.runScript(clazz, SpringBeanUtils.getApplicationContext(), params);
JSONObject result = new JSONObject();
JSONObject response = new JSONObject();
response.put("data", obj);
response.put("success", "true");
result.put("response", response);
return result;
}
}
public class GroovyUtil {
public static Object runScript(Class<?> clazz, ApplicationContext applicationContext, String params) {
Map<String, Object> groovyParams = new HashMap<>(6);
groovyParams.put("context", applicationContext);
groovyParams.put("data", params);
try {
GroovyObject instance = (GroovyObject) clazz.newInstance();
Object result = instance.invokeMethod("execute", groovyParams);
return result;
} catch (Exception e) {
return e.getMessage();
}
}
public static Class<?> parseClass(String script) {
GroovyClassLoader classLoader = new GroovyClassLoader(Thread.currentThread().getContextClassLoader());
Class<?> clazz = classLoader.parseClass(script);
return clazz;
}
}
脚本内容
package com.example.concrete.starter.third;

import com.example.concrete.common.domain.UserDTO;
import com.example.concrete.starter.service.GreetService;
import org.springframework.context.ApplicationContext;
import java.util.Map;
public class GreetScript {
public String execute(Map<String, Object> contextMap) {
ApplicationContext applicationContext = (ApplicationContext) contextMap.get("context");
String jsonStr = (String) contextMap.get("data");
UserDTO userDTO = JSON.parseObject(jsonStr, UserDTO.class);
GreetService greetService = (GreetService) applicationContext.getBean("greetServiceImpl");
return greetService.greeting(userDTO, "groovy-script");
}
}
