如何在jhipster微服务架构中使用会话范围的bean

Question

我的会话范围bean：

@Scope(value = "session", proxyMode = ScopedProxyMode.TARGET_CLASS)
@Component
public class AuthNodes {
    private String authNodes;
    public String getAuthNodes() {
        return authNodes;
    }
    public void setAuthNodes(String authNodes) {
        this.authNodes = authNodes;
    }
}

注入到JHipster生成的微服务的REST控制器中：

@RestController
@RequestMapping("/api")
public class NodeResource {
    @Autowired
    private AuthNodes authNodes;
    ...

    @GetMapping("/nodes-and-children/{user:.+}")
    @Timed
    public ResponseEntity<List<Node>> getFilteredNodesAndChildren(@PathVariable String user,
        @ApiParam Pageable pageable) {
        ...
        String hosts = authNodes.getAuthNodes();
        if (hosts == null) {
            authNodes.setAuthNodes("my user's authorized node names");
        }
        ...

但是在每次调用时，先前设置的值都会丢失，authNodes.getAuthNodes（）将返回null。

有什么问题？

谢谢，Mic
