我正在尝试自动连接daoImpl类中的数据源对象，并在daoImple类中使用@Component。 library(shiny)
library(datasets)
library(shinyWidgets)
statesDF <- data.frame(region = state.region, name = state.name, area = state.area, stringsAsFactors = FALSE)
ui <- fluidPage(
radioButtons(inputId = 'selected_group', label = 'group', choices = unique(statesDF$region)),
pickerInput(inputId = 'selected_subgroup', label = 'subgroup', choices = NULL, selected = NULL, multiple = TRUE)
)
server <- function(input, output, session) {
filteredChoices <- reactive({
statesDF$name[statesDF$region == input$selected_group]
})
observeEvent(filteredChoices(), {
updatePickerInput(session, inputId = 'selected_subgroup', label = 'subgroup', choices = filteredChoices(), selected = filteredChoices())
})
}
shinyApp(ui = ui, server = server)
在DaoImpl类中
Caused by: java.lang.IllegalArgumentException: 'dataSource' or 'jdbcTemplate' is required
