SpringSocial提供了了以下三个服务，我们要做的仅仅是调用它们的服务，但是SpringSocial仅仅只提供了数据，没有提供视图
⒈拿到所有社交网站与业务系统的绑定信息
SpringSocial已经提供了相应的数据，但并没有提供视图，相关的代码写在ConnectController中，核心代码如下：
1 @RequestMapping( 2 method = {RequestMethod.GET} 3 ) 4 public String connectionStatus(NativeWebRequest request, Model model) { 5 this.setNoCache(request); 6 this.processFlash(request, model); 7 Map<String, List<Connection<?>>> connections = this.connectionRepository.findAllConnections(); 8 model.addAttribute("providerIds", this.connectionFactoryLocator.registeredProviderIds()); 9 model.addAttribute("connectionMap", connections); 10 return this.connectView(); 11 }
这个方法的返回值是一个View，路径是connect/status，我们只需要实现这个视图就可以了。
1 package cn.coreqi.social; 2 3 import com.fasterxml.jackson.databind.ObjectMapper; 4 import org.apache.commons.collections4.CollectionUtils; 5 import org.springframework.beans.factory.annotation.Autowired; 6 import org.springframework.social.connect.Connection; 7 import org.springframework.stereotype.Component; 8 import org.springframework.web.servlet.view.AbstractView; 9 10 import javax.servlet.http.HttpServletRequest; 11 import javax.servlet.http.HttpServletResponse; 12 import java.util.HashMap; 13 import java.util.List; 14 import java.util.Map; 15 16 @Component("connect/status") 17 public class CoreqiConnectionStatusView extends AbstractView { 18 19 @Autowired 20 private ObjectMapper objectMapper; 21 @Override 22 protected void renderMergedOutputModel(Map<String, Object> map, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception { 23 Map<String, List<Connection<?>>> connections = (Map<String, List<Connection<?>>>) map.get("connectionMap"); 24 Map<String,Boolean> result = new HashMap<>(); 25 for(String key:connections.keySet()){ 26 result.put(key, CollectionUtils.isNotEmpty(connections.get(key))); 27 } 28 httpServletResponse.setContentType("application/json;charset=UTF-8"); 29 httpServletResponse.getWriter().write(objectMapper.writeValueAsString(result)); 30 } 31 }
⒉业务系统与社交网站绑定
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>绑定</title> 6 </head> 7 <body> 8 <h2>标准绑定页面</h2> 9 <!--form 的action地址是固定的格式，前面是connect，后面是OAuth的providerId--> 10 <form action="/connect/weixin" method="post"> 11 <button type="submit">绑定微信</button> 12 </form> 13 </body> 14 </html>
绑定成功后跳转到connect/{providerId}Connected这个视图，上面的例子将会跳转到connect/weixinConnected这个视图上。
1 package cn.coreqi.social; 2 3 import org.springframework.stereotype.Component; 4 import org.springframework.web.servlet.view.AbstractView; 5 import javax.servlet.http.HttpServletRequest; 6 import javax.servlet.http.HttpServletResponse; 7 import java.util.Map; 8 9 @Component("connect/weixinConnect,connect/weixinConnected") //如果当前绑定成功的视图需要重用，请注释@Component注解 10 //在配置类中以@Bean的形式注册当前类，并指定多个不同的name属性。 11 public class CoreqiConnectionView extends AbstractView { 12 13 @Override 14 protected void renderMergedOutputModel(Map<String, Object> map, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception { 15 httpServletResponse.setContentType("text/html;charset=UTF-8"); 16 if(map.get("connection") == null){ 17 httpServletResponse.getWriter().write("<h3>解绑成功</h3>"); 18 }else{ 19 httpServletResponse.getWriter().write("<h3>绑定成功</h3>"); 20 } 21 } 22 }
⒊业务系统与社交网站解绑
1 <!DOCTYPE html> 2 <html lang="en"> 3 <head> 4 <meta charset="UTF-8"> 5 <title>绑定</title> 6 </head> 7 <body> 8 <h2>标准绑定页面</h2> 9 <!--form 的action地址是固定的格式，前面是connect，后面是OAuth的providerId--> 10 <!--解除绑定只需将post请求改为delete请求，当然，form表单是无法发送delete请求的，我只是告诉你--> 11 <form action="/connect/weixin" method="delete"> 12 <button type="submit">绑定微信</button> 13 </form> 14 </body> 15 </html>
解绑成功后跳转到connect/{providerId}Connect这个视图（相较于绑定，视图名去掉了ed而已），上面的例子将会跳转到connect/weixinConnect这个视图上。
1 package cn.coreqi.social; 2 3 import org.springframework.stereotype.Component; 4 import org.springframework.web.servlet.view.AbstractView; 5 import javax.servlet.http.HttpServletRequest; 6 import javax.servlet.http.HttpServletResponse; 7 import java.util.Map; 8 9 @Component("connect/weixinConnect,connect/weixinConnected") //如果当前绑定成功的视图需要重用，请注释@Component注解 10 //在配置类中以@Bean的形式注册当前类，并指定多个不同的name属性。 11 public class CoreqiConnectionView extends AbstractView { 12 13 @Override 14 protected void renderMergedOutputModel(Map<String, Object> map, HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse) throws Exception { 15 httpServletResponse.setContentType("text/html;charset=UTF-8"); 16 if(map.get("connection") == null){ 17 httpServletResponse.getWriter().write("<h3>解绑成功</h3>"); 18 }else{ 19 httpServletResponse.getWriter().write("<h3>绑定成功</h3>"); 20 } 21 } 22 }
