Question

我尝试运行spring boot应用程序，该应用程序将在静态文件夹中返回HTML静态文件，问题是：每次加载页面时：127.0.0.1我得到的是字符串“ bakara”，而不是HTML文件bakara.html。当我加载127.0.0.1/bakara.html时，我得到了bakara.html文件

pom.xml：

library( data.table )
#create two data.tables
dt1 <- as.data.table( DF1 )
dt2 <- as.data.table( DF2 )
#add suffixes to columns, to identify them after the join
names( dt1 ) <- paste0( names( dt1 ), ".dt1" )
names( dt2 ) <- paste0( names( dt2 ), ".dt2" )
#save column order for later
colorder <- c( names( dt1 ), names( dt2 ) )
#set date-time as poosix-stamps
dt1[, `:=`( start.join = as.POSIXct( paste0( Date.dt1, TrackTime.dt1 ), format = "%d/%m/%Y%H:%M:%S" ),
            end.join = as.POSIXct( paste0( Date.dt1, TrackTime.dt1 ), format = "%d/%m/%Y%H:%M:%S" ) )]
dt2[, `:=`( start.join = as.POSIXct( paste0( DATE_SIGHT.dt2, TIME_START.dt2 ), format = "%d-%b-%y%H:%M:%S" ),
            end.join = as.POSIXct( paste0( DATE_SIGHT.dt2, TIME_END.dt2 ), format = "%d-%b-%y%H:%M:%S" ) )]
#set key on dt2
setkey( dt2, start.join, end.join )
#perform the overlap join
result <- foverlaps( dt1, dt2, type = "within", nomatch = 0L )
#drop the join columns
result[, grep( ".join$", names( result ) ) := NULL]
#set the order of columns right
setcolorder( result, colorder )

#       X.dt1    Y.dt1 Date.dt1 Time.dt1 TrackTime.dt1 DATE_SIGHT.dt2 GROUP_SIGHT.dt2 TIME_START.dt2 TIME_END.dt2 GRP_SIZE.dt2

HomeController.java：

#spring.mvc.view.prefix=/static/
#spring.mvc.view.suffix=.html

spring.mvc.view.prefix=/static
spring.mvc.view.suffix=.html

项目结构：

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.*;

@Controller
public class HomeController {

    @RequestMapping("/")
    @ResponseBody
    public String welcome() {
        return "bakara";
    }
}

Answer 1

默认情况下，Spring Boot看起来适合templates文件夹static文件夹中的html模板，适用于css and js等其他文件。尝试将src/main/resources/templates文件夹中的html文件移动到从控制器方法中删除@ResponseBody，并从应用程序属性spring.mvc.view.prefix=/static中删除它。我希望它能起作用。

Answer 2

我有同样的问题。仅通过返回带有html文件名的String便无法返回html。对我来说，它只能使用ModelAndView来工作，在您的情况下，它看起来像这样：

@RequestMapping("/")
public ModelAndView welcome() {
    ModelAndView modelAndView = new ModelAndView();
    modelAndView.setViewName("bakara");
    return modelAndView;
}

有人说这种问题是因为jdk版本而发生的。我使用的是jdk14。

Answer 3

使用注解@ResponseBody时，实际上是告诉spring不要尝试使用返回的名称查找视图。如果需要html，只需从控制器方法中删除注释。

Answer 4

Sub DeleteSAC() Dim count As Integer Dim i As Integer Dim j As Integer Sheets(1).Select lastRow = ActiveSheet.Cells(Rows.count, "B").End(xlUp).Row 'have to keep data in a table for this to actually work as it ctrls+left to the table, which will end where the very last text of any row is lastColumn = ActiveSheet.Cells(1, Columns.count).End(xlToLeft).Column count = Sheet2.Cells(1, 7).Value i = 2 j = lastColumn For i = 2 To lastRow For j = lastColumn To 1 If Sheet1.Cells(i, j) = "SAC" Then count = count - 1 GoTo NextIteration End If Next j NextIteration: Next i Sheet2.Cells(1, 7) = count End Sub与VS @Controller

@RestController用于将类标记为Spring MVC Controller。
@Controller是一个便捷注释，它仅添加了@RestController和@Controller注释。

因此，在您的情况下，只需从HomeController.java中的@ResponseBody方法中删除@ResponseBody注释，就足以获得所需的输出。
