Question

struts2注解 返回json时 params = {"includeProperties" 怎么设置多个对象

params = {"includeProperties"} 和excludeProperties 怎么这设置多个啊??

Answer 1

params={"key1","value1","key2", "value2"}
如：@Result(name="success", type="json", params={"root","action","includeProperties", "result"}),

Answer 2

这里有个例子 不知道是不是你想要得效果；
StringBuffer sb = new StringBuffer();
sb.append("[");
for(int i=0;i<10;i++){

if(i>0){
sb.append(",");
}
sb.append("{");
sb.append("\"id\":\"" + i + "\",");
sb.append("\"name\":\"name" + i + "\",");
sb.append("\"age\":\"" + i*10 + "\"");
sb.append("}");
}
response.setCharacterEncoding("UTF-8");
response.getWriter().write(sb.toString());
打印出来的格式这样：
[{"id":"1","name":"name1","age":"10"},
{"id":"2","name":"name2","age":"20"},
{"id":"3","name":"name3","age":"30"},
