java - Domino 代理和 GSON - 访问被拒绝

Question

在 Java 代理中，我想使用 GSON 来解析 json。但是当我尝试时:

String jsonReceived = "{'product':'IBM Domino','args':{'since':'1970','current':'9.0.2'}}";
Product product = (Product) gson.fromJson(jsonReceived, Product.class);

我收到消息:

java.security.AccessControlException:访问被拒绝(“java.lang.reflect.ReflectPermission”“suppressAccessChecks”)

我最近将 java 策略更改为最大值:

grant { 
    permission java.security.AllPermission;
}

那么是什么限制了我呢？

完整代码如下:

import lotus.domino.*;

import com.google.gson.Gson;
import com.google.gson.GsonBuilder;
import com.google.gson.JsonParseException;

public class JavaAgent extends AgentBase {

    public void NotesMain() throws JsonParseException{

        String msg = null;

        lotus.domino.Session session = getSession();
        OpenLogItem oli = new OpenLogItem(session);

        try {

            AgentContext agentContext = session.getAgentContext();

            msg = "Agent " + agentContext.getCurrentAgent().getName() + " using runtime version:" + System.getProperty("java.runtime.version");
            oli.logEvent(msg, OpenLogItem.SEVERITY_LOW, null);

            Gson gson = new GsonBuilder().create();

            msg = "after new Gson()";
            oli.logEvent(msg, OpenLogItem.SEVERITY_LOW, null);

            String jsonReceived = "{'product':'IBM Domino'}";
            Product product = (Product) gson.fromJson(jsonReceived, Product.class);

            msg = "after gson.fromJson";
            oli.logEvent(msg, OpenLogItem.SEVERITY_LOW, null);


      } catch(Exception e) {
          oli.logError(e);
      }
   }

    public class Product{
        String product;
        String msg = null;

        lotus.domino.Session session = getSession();
        OpenLogItem oli = new OpenLogItem(session);

        public Product(){
            msg = "Product() // constructor";
            oli.logEvent(msg, OpenLogItem.SEVERITY_LOW, null);
        }

        public String getProduct() {
            return product;
        }

        public void setProduct(String product) {
            this.product = product;
        }

        /*@Override
        public String toString() {
            // TODO Auto-generated method stub
            return "product: " + getProduct();
        }*/


    }
}

我刚刚使用 Java 代理通过 GSON 解析 JSON。遇到同样的错误，创建具有相同完全权限的 java.pol 文件并且它有效。请记住设置安全性以允许对代理进行受限操作
