大家好，我这里有一个大问题。我的 Controller 中的 session 无法正常工作。我的目标是为每个 session 拥有一个 comp 对象，但我每次都会得到相同的 comp(comp 仅初始化一次，而不是每个 session )。
示例:
Mozilla: 首先我的comp是空的。当我在一个屏幕中选择一个组件时，新组件将被初始化，一切正常。
Chrome: 当我到达想要选择的屏幕时，我的组件已经初始化(Mozilla 组件)，因此当我选择我的组件时，来自 mozilla 的组件将被覆盖。
Controller :
package com.test;
@SessionAttributes({"comp", "userDetails"})
@Controller
@RequestMapping(value="/arep")
public class ARepController{
@Autowired AdmUserDetails userDetails;
@Autowired
private ARepService aRepService;
@Autowired
private Component comp;
}
组件:
package com.test;
@Component
@Scope(proxyMode = ScopedProxyMode.TARGET_CLASS, value = "session")
public class Component implements Serializable {
private static final long serialVersionUID = 587780902400791285L;
private List<Component Item> items = new ArrayList<ComponentItem>();
private Integer length;
private Integer height;
private Integer depth;
public Component () {
}
public Component (Integer length, Integer height,Integer depth) {
this.length = length;
this.height = height;
this.depth = depth;
}
}

我只复制了对我来说至关重要的代码。首先，我要感谢所有愿意花时间帮助我的人。
最佳答案
您还需要使 Controller bean session 具有范围
关于java - Spring 没有为每个 session 初始化一个对象，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/25342074/
