SpringSocial对于绑定状态提供了数据支持，需要完善视图功能：
数据访问地址：/connect
即访问org.springframework.social.connect.web.ConnectController中
connectionStatus(NativeWebRequest request, Model model)方法
新建数据视图处理工具类DemoConnectionStatusView：
/**
* 绑定状态视图实现
*
* @author zhaohaibin
*/
@Component("connect/status")
public class DemoConnectionStatusView extends AbstractView {
@Autowired
private ObjectMapper objectMapper;
/**
* org.springframework.social.connect.web.ConnectController
* connectionStatus(NativeWebRequest request, Model model)
* @param map
* @param request
* @param response
* @throws Exception
*/
@Override
protected void renderMergedOutputModel(Map<String, Object> map, HttpServletRequest request, HttpServletResponse response) throws Exception {
Map<String, List<Connection<?>>> connections = (Map<String, List<Connection<?>>>) map.get("connectionMap");
Map<String, Boolean> result = new HashMap<>();
for (String key : connections.keySet()) {
result.put(key, CollectionUtils.isNotEmpty(connections.get(key)));
}
response.setContentType("application/json;charset=UTF-8");
response.getWriter().write(objectMapper.writeValueAsString(result));
}
}
新建绑定结果视图工具类DemoConnectView：
/**
* 第三方通用绑定结果处理
*
* @author zhaohaibin
*/
public class DemoConnectView extends AbstractView {
@Override
protected void renderMergedOutputModel(Map<String, Object> map, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception {
httpServletResponse.setContentType("text/html;charset=UTF-8");
if (null == map.get("connection")) {
httpServletResponse.getWriter().write("<h3>绑定成功</h3>");
} else {
httpServletResponse.getWriter().write("<h3>解绑成功</h3>");
}
}
}
配置：
更新WeixinAutoConfiguration：
/**
* 绑定结果配置
* 绑定：weixinConnect，解绑：weixinConnected
* @return
*/
@Bean({"connect/weixinConnect", "connect/weixinConnected"})
@ConditionalOnMissingBean(name = "weixinConnectedView")
public View weixinConnectedView() {
return new DemoConnectView();
}
新建绑定页面：
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>第三方绑定</title>
</head>
<body>
<h2>标准绑定页面</h2>
<!--绑定请求是post，解绑请求是delete，需要依赖工具测试解绑-->
<form action="connect/weixin" method="post">
<input type="submit" value="绑定微信">
</form>
</body>
</html>
问题排查：
// 访问/connect始终404，怀疑对应ConnectController未生效，查资料后增加如下实现：
/**
* 问题：应用扫不到@Controller而无@ComponentScan注解的
* org.springframework.social.connect.web.ConnectController
*
* 因为：@SpringBootApplication注解等价于@Configuration, @EnableAutoConfiguration and @ComponentScan
*
* 所以：通过继承定义组件使应用加载
*
* @author zhaohaibin
*/
@Component
public class DefaultConnectController extends ConnectController {
public DefaultConnectController(ConnectionFactoryLocator connectionFactoryLocator, ConnectionRepository connectionRepository) {
super(connectionFactoryLocator, connectionRepository);
}
}
