如何访问胸腺中的春季bean范围

Question

我已经定义了我的对象

  @Component
  @Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS) 
  public class MySession {
      private String message;
     // getter setter
  }

当我尝试从胸腺访问时，它失败了。

<p th:text="${mySession.message}"></p>

解决方案

通过弹簧豆访问

 <p th:text="${@mySession.getMessage()}"></p>

Answer 1

session.setAttribute("mySessionAttribute", "someValue");

您可以访问直接会话属性。

${#session.getAttribute('mySessionAttribute')}

Answer 2

例如session bean

@Component
@SessionScope
public class State implements Serializable {
    private String pdfPropertyName;
    public String getPdfPropertyName() {
        return pdfPropertyName;
    }
    public void setPdfPropertyName(String pdfPropertyName) {
        this.pdfPropertyName = pdfPropertyName;
    }
}

在控制器中

@Controller
@RequestMapping("uploadPdf")
public class UploadPdfController {
    @Autowired State state;
    @ModelAttribute("pdfPropertyName")
    public String getPdfPropertyName() {
        return state.getPdfPropertyName();
    }
}

可以通过

访问

<span th:text="${pdfPropertyName}"></span>
