Question

我已经在tomcat服务器的vm中部署了spring boot应用程序。当我加载页面时，我只看到静态部分，没有任何uri映射到控制器中的ajax函数似乎在这里工作。但同样在我的本地应用程序中工作正常。谁能请帮忙。我正在附上我的休息控制器类的代码。

import org.springframework.data.rest.webmvc.RepositoryRestController;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.bind.annotation.ResponseBody;
import org.springframework.web.bind.annotation.RestController;
import org.springframework.web.servlet.ModelAndView;

import com.abc.xyz.util.DLCUtils;

import java.util.List;


@RestController

public class HomeController {

    @RequestMapping("/home")
    public ModelAndView home(Model model) {
        int lastWeekInMonth = 0;
        lastWeekInMonth = DLCUtils.getLastWeekInMonth(2, 2016);
        System.out.println("last week"+lastWeekInMonth);
        model.addAttribute("lastweek", lastWeekInMonth);
        ModelAndView mav = new ModelAndView("/index");
        return mav;

        monthnumber = DLCUtils.getMonthNumber(month.toUpperCase());
        //System.out.println("last week in lastweek"+lastWeekInMonth);
        return monthnumber;
    }



    @RequestMapping(value="/getRangeOfDate",method=RequestMethod.GET)
    @ResponseBody
    public String getRangeOfDate(@RequestParam("week") int week,@RequestParam("month") int month,@RequestParam("year") int year) {

        StringBuilder submitList = new StringBuilder("");
        Date fd=null,ld=null;
        dateRange = DLCUtils.getAllDays(week, month, year);

            if (i == 0) {
                fd = dateRange.get(0);
            }

        }
        String firstdate = null;

        int fdate = 0;
        int ldate = 0;
        firstdate = fd.toString();
        lastdate = ld.toString();
        String firstdate1 = firstdate.substring(8, 10);

        String pattern = "yyyy/MM/dd";
        for (Date date : lstDates) {

        dayOfWeek=DLCUtils.getDayOfTheWeek(date);
        submitList.append(dayOfWeek);submitList.append(",");submitList.append(formattedDate);submitList.append("+");
        }
        return submitList.toString();
    }

    public String populatedetails(@RequestParam("name") String name,@RequestParam("Id") String id,@RequestParam("Email") String email){

        StringBuilder submitList = new StringBuilder("");
        String place="Bangalore";String joiningdate="2014-01-01";String enddate="9999-12-31";String rights="Employee";String status="Active";String dept="EBU";String manager="David";
        submitList.append("Name"+"+"+name+","+"GlobalId"+"+"+id+","+"Email"+"+"+email+","+"Location"+"+"+place+","+"Joining Date"+"+"+joiningdate+","+"Resignation Date"+"+"+enddate+","+"Rights"+"+"+rights+",");


        submitList.append("Status"+"+"+status+","+"Division"+"+"+dept+","+"Manager"+"+"+manager+","+"Projects"+"+");
        submitList.append("SPT"+".");submitList.append("SPM"+".");submitList.append("DLC"+".");submitList.append("TEST1"+".");submitList.append("TEST2"+".");submitList.append("TEST3"+".");
        return submitList.toString();
    }   
}

出于这一点，只有那些返回模型并查看woorks和所有其他映射到从angular js ajax调用调用的函数的函数都没有被调用，它在控制台中显示

angular.js:8611 GET http://172.16.77.83:8083/getCurrentWeek 404 (Not Found)

同样适用于其他电话。因此，我的html页面中的数据没有正确填充。相同的应用程序在我的本地机器上工作正常。仅在此外部虚拟机中，它才显示此问题。

添加js文件的ajax调用代码。

function getCurrentWeek(){
        console.log("in ajax");

        $http({
            method : "GET",
            url : "/getCurrentWeek"
        }).then(function mySucces(response) {
            $scope.currentWeek=response.data;
              var j=parseInt($scope.currentWeek)-1;


              $('table.ui-datepicker-calendar tr:eq('+$scope.currentWeek+')').css({"border":"3px solid #e1e1e1"});
              var weekVal=$('#weekvalues a')[j];
             weekVal.style.border="3px solid #50a8e5";
              weekVal.style.paddingRight="2px";
              weekVal.style.paddingLeft="2px";
              weekVal.style.paddingTop="1px";

        }, function myError(response) {
            //$scope.dateRange = response.statusText;
        });

    }

谢谢， Poorna。

在我看来，当您在Tomcat容器（VM内部）上进行部署时，您正在使用不同的上下文路径。如果使用mvn spring-boot:run在本地运行应用程序，或者在未设置server.contextPath属性的情况下启动JAR，则可能在嵌入式容器中的根上下文中运行它。

网址http://172.16.77.83:8083/getCurrentWeek在该根上下文上运行，而在Tomcat上，您可能需要转到http://172.16.77.83:8083/MyApplicationNam/getCurrentWeek。

要解决这个问题，有一些解决方案：

<强> 1。在根上下文中部署应用程序：

在将WAR部署到Tomcat之前将WAR重命名为ROOT.war
更改server.xml

查看此答案以获取更多相关信息：Deploying my application at the root in Tomcat

<强> 2。使用相对URL（可能是最佳解决方案）：

通过使用相对URL，您将始终根据HTML页面进行相对工作。如果HTML页面位于同一个应用程序中，则上下文路径也将应用于HTML页面，因此相对于HTML页面，REST API应始终保持不变。

$http({
    method : "GET",
    url : "./getCurrentWeek"
})

Answer 2

您的应用程序是一个RESTful服务部署在tomcat服务器上。并且您尝试在部署在不同服务器上的AngularJS中访问这些服务。

您必须添加CORS过滤（CROSS域原始访问权限），才能访问HTTP谓词以进行跨服务。（域到域访问）在类路径中添加以下Bean，它可以正常工作。

@Component
public class CORSFilter implements Filter {

    public void doFilter(ServletRequest req, ServletResponse res, FilterChain chain) throws IOException, ServletException {
        HttpServletResponse response = (HttpServletResponse) res;
        response.setHeader("Access-Control-Allow-Origin", "*");
        response.setHeader("Access-Control-Allow-Methods", "POST, GET, PUT, OPTIONS, DELETE");
        response.setHeader("Access-Control-Max-Age", "3600");
        response.setHeader("Access-Control-Allow-Headers", "Origin, X-Requested-With, Content-Type, Accept");
        chain.doFilter(req, res);
    }

    public void init(FilterConfig filterConfig) {}

    public void destroy() {}

}

某些功能的控制器映射在部署的Spring引导应用程序中不起作用
