Swagger UI still showing the example

Question

I want to use Swagger for my RESTFul API Documentation from Go and Gin.

I have this code in main.go: package main

import (
    "gowebservice/config"
    "gowebservice/controllers"

    "github.com/gin-gonic/gin"
    swaggerFiles "github.com/swaggo/files"
    ginSwagger "github.com/swaggo/gin-swagger"

    _ "github.com/swaggo/gin-swagger/example/basic/docs"
)

// @title Students API
// @version 1.0
// @description This is a basic API Students using Gin and Gorm.

// @host localhost:8080
// @BasePath /

func main() {
    r := gin.Default()

    config.ConnectDatabase()

    v1 := r.Group("/api/v1")
    {
        v1.GET("students/all", controllers.GetStudents)
    }

    r.GET("/swagger/*any", ginSwagger.WrapHandler(swaggerFiles.Handler))

    r.Run()
}

and this is my endpoint that have GET method:

package controllers

import (
    "gowebservice/config"
    "gowebservice/models"
    "net/http"

    "github.com/gin-gonic/gin"
)

// GetStudents godoc
// @Summary Show a list of students
// @Accept  json
// @Produce  json
// @Router /students [get]
func GetStudents(c *gin.Context) {
    var students []models.Student

    if err := config.DB.Find(&students).Error; err != nil {
        c.JSON(http.StatusBadRequest, gin.H{"error": "Record not found!"})
        return
    }
    c.JSON(http.StatusOK, students)
}

When I used swag init and go run main.go, Swagger UI still showing the example not my endpoint.

Anyone can help me?

I ran into this too 😅

The issue is that we imported the basic example docs:

import (
    ...

    _ "github.com/swaggo/gin-swagger/example/basic/docs"
)

You need to change that to the docs package that was generated by swag init. Assuming your module name is gowebservice, then:

import (
    ...

    _ "gowebservice/docs"
)

Running go run main.go after that should make Swagger UI find your own documentation instead! :D
