如何创建ServletContext的模拟属性？

import javax.servlet.ServletContext;
import java.util.HashMap;
import java.util.Map;

public class MockServletContext implements ServletContext {
    private Map<String, Object> attributes;

    public MockServletContext() {
        attributes = new HashMap<>();
    }

    @Override
    public void setAttribute(String name, Object value) {
        attributes.put(name, value);
    }

    @Override
    public Object getAttribute(String name) {
        return attributes.get(name);
    }

    // 其他方法的实现...

    // 示例使用腾讯云的产品链接地址
    public static void main(String[] args) {
        MockServletContext context = new MockServletContext();
        context.setAttribute("key", "value");

        // 获取属性值
        Object value = context.getAttribute("key");
        System.out.println(value);
    }
}
