2、权限和单点配置信息

1. sso.enable=true
2. rbac.enable=true
3. rbac.url=http://192.168.21.46:8080/
4. weixin.url=http://192.168.28.111:8181/
5. sso.casServerUrlPrefix = http://192.168.21.46:8080/cas/
6. sso.logoutUrl = ${sso.casServerUrlPrefix}logout
7. sso.client.serverName=http://localhost:8080

3、登录拦截filter，将单点系统存放在session中的用户信息拿到后做处理再添加系统所需用户信息在session中

1. publicfinalvoid doFilter(ServletRequest servletRequest,ServletResponse servletResponse,FilterChain filterChain)throwsIOException,ServletException{
2. HttpServletRequest request =(HttpServletRequest)servletRequest;
3. HttpServletResponse response =(HttpServletResponse)servletResponse;
4. HttpSession session = request.getSession(false);
5. Assertion assertion = session !=null?(Assertion)session.getAttribute("_const_cas_assertion_"):null;
6. if(assertion !=null){
7. String username = assertion.getPrincipal().getName();
8. IUserService userService =(IUserService)ServiceLocator.getService("userService");
9. Map<String,Object> queryParams =newHashMap<String,Object>();
10. queryParams.put("username",username);
11. List<User> users = userService.find(queryParams);
12. SessionUtil.set(request,SessionUtil.USER_SESSION_NAME,users.get(0));
13. filterChain.doFilter(request, response);
14. }else{
15. String serviceUrl =this.constructServiceUrl(request, response);
16. boolean isInWhiteList =false;
17. if(excludePaths!=null&& excludePaths.size()>0&& serviceUrl !=null){
18. for(String path : excludePaths){
19. if(CommonUtils.isNotBlank(path)){
20. isInWhiteList =StringUtil.isIn(path,serviceUrl);
21. if(isInWhiteList){
22. break;
23. }
24. }
25. }
26. }
27. String ticket =CommonUtils.safeGetParameter(request,this.getArtifactParameterName());
28. boolean wasGatewayed =this.gatewayStorage.hasGatewayedAlready(request, serviceUrl);
29. if(isInWhiteList){
30. filterChain.doFilter(request, response);
31. }elseif(!CommonUtils.isNotBlank(ticket)&&!wasGatewayed){
32. this.log.debug("no ticket and no assertion found");
33. String modifiedServiceUrl;
34. if(this.gateway){
35. this.log.debug("setting gateway attribute in session");
36. modifiedServiceUrl =this.gatewayStorage.storeGatewayInformation(request, serviceUrl);
37. }else{
38. modifiedServiceUrl = serviceUrl;
39. }
41. if(this.log.isDebugEnabled()){
42. this.log.debug("Constructed service url: "+ modifiedServiceUrl);
43. }
45. String urlToRedirectTo =CommonUtils.constructRedirectUrl(this.casServerLoginUrl,this.getServiceParameterName(), modifiedServiceUrl,this.renew,this.gateway);
46. if(this.log.isDebugEnabled()){
47. this.log.debug("redirecting to \""+ urlToRedirectTo +"\"");
48. }
50. response.sendRedirect(urlToRedirectTo);
51. }else{
52. filterChain.doFilter(request, response);
53. }
54. }
55. }

4、修改我们的首页控制器，获取session中的用户信息，处理存放到变量集合

1. package cn.com.bmsoft.smartcity.common.controller;
3. import cn.com.bmsoft.smartcity.common.IContextService;
4. import cn.com.bmsoft.smartcity.common.TreeModel;
5. import cn.com.bmsoft.smartcity.common.domain.User;
6. import cn.com.bmsoft.smartcity.common.util.SessionUtil;
7. import com.bmsoft.jasig.cas.client.util.CASClientUtils;
8. import org.springframework.beans.factory.annotation.Autowired;
9. import org.springframework.stereotype.Controller;
10. import org.springframework.web.bind.annotation.RequestMapping;
11. import org.springframework.web.bind.annotation.RequestMethod;
12. import org.springframework.web.bind.annotation.ResponseBody;
13. import org.springframework.web.servlet.ModelAndView;
15. import javax.servlet.http.HttpServletRequest;
16. import java.util.HashMap;
17. import java.util.Map;
20. @Controller("home")
21. publicclassHomeController{
23. @Autowired
24. privateIContextService contextService;
26. @RequestMapping(value={"","/home/index","/home"})
27. publicModelAndView home(HttpServletRequest request){
28. Map<String,String> map=newHashMap<String,String>();
29. User user =(User)SessionUtil.get(request,SessionUtil.USER_SESSION_NAME);
30. map.put("userName", user.getName());
31. returnnewModelAndView("home/index",map);
32. }
34. @ResponseBody
35. @RequestMapping(value ={"/home/menu"}, method =RequestMethod.GET)
36. publicTreeModel getMenu(HttpServletRequest request){
37. User user =(User)SessionUtil.get(request,SessionUtil.USER_SESSION_NAME);
38. returnthis.contextService.getMenu(user.getUsername());
39. }
42. }

5、退出控制器，退出按钮方法修改

1. package cn.com.bmsoft.smartcity.common.controller;
3. import cn.com.bmsoft.smartcity.common.util.SessionUtil;
4. import org.springframework.beans.factory.annotation.Value;
5. import org.springframework.stereotype.Controller;
6. import org.springframework.web.bind.annotation.RequestMapping;
7. import org.springframework.web.servlet.ModelAndView;
8. import org.springframework.web.servlet.view.RedirectView;
10. import javax.servlet.http.HttpServletRequest;
12. /**
13. * Created by Administrator on 2016/4/18.
14. */
15. @Controller
16. @RequestMapping(value ="/accounts")
17. publicclassLogoutController{
19. @Value("${sso.logoutUrl}")
20. privateString logoutUrl;
21. @Value("${sso.client.serverName}")
22. privateString serverName;
24. // @RequestMapping("/logout")
25. // public ModelAndView logout(ModelAndView view, HttpServletRequest request) {
26. // SessionUtil.destroy(request,SessionUtil.USER_SESSION_NAME);
27. //// request.getSession().invalidate();
28. // request.setAttribute("message","");
29. // String logout = logoutUrl+"?service="+serverName+request.getContextPath()+"/";
30. // view.setView(new RedirectView(logout, false));
31. // return view;
32. // }
34. @RequestMapping("/logout")
35. publicString logout(HttpServletRequest request){
36. SessionUtil.destroy(request,SessionUtil.USER_SESSION_NAME);
37. // request.getSession().invalidate();
38. request.setAttribute("message","");
39. return"account/login";
40. }
41. }
