目錄結(jié)構(gòu)

1. 引入 swagger3.0 依賴(lài)
<!-- swagger -->
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-boot-starter</artifactId>
<version>3.0.0</version>
</dependency>
2. 配置 swagger3.0

3. 開(kāi)啟 swagger(@EnableOpenApi注解添加到啟動(dòng)類(lèi))
/**

@EnableOpenApi
@SpringBootApplication
@MapperScan("com.test.wl.mapper")
public class SpringbootSwaggerApplication {
public static void main(String[] args) {
SpringApplication.run(SpringbootSwaggerApplication.class, args);
}
}
4. 編寫(xiě) Controller
StudentController.java
package com.test.wl.controller;
import com.test.wl.entity.Student;
import com.test.wl.service.StudentService;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.validation.annotation.Validated;
import org.springframework.web.bind.annotation.*;
import java.util.List;
/**
* @author wl
* @date 2021年5月21日 15:15:26
*/
@Api(tags = "學(xué)生表接口")
@RestController
@RequestMapping("/v3/student")
public class StudentController {
@Autowired
private StudentService studentService;
@ApiOperation(value = "查詢所有學(xué)生信息", notes = "查詢所有學(xué)生信息", httpMethod = "GET")
@GetMapping("/all")
public List<Student> allStudents() {
return studentService.selectStudents();
}
@ApiOperation(value = "增加學(xué)生信息", notes = "增加學(xué)生信息", httpMethod = "POST")
@PostMapping("/add")
public String addStudents(@Validated @RequestBody Student student) {
return studentService.saveStudent(student);
}
@ApiOperation(value = "修改學(xué)生信息", notes = "修改學(xué)生信息", httpMethod = "PUT")
@PutMapping("/update")
public String updateStudents(@Validated @RequestBody Student student) {
return studentService.updateStudent(student);
}
@ApiOperation(value = "刪除學(xué)生信息", notes = "刪除學(xué)生信息", httpMethod = "DELETE")
@DeleteMapping("/delete/{studentId}")
public String deleteStudents(@Validated @PathVariable(name = "studentId") String studentId) {
return studentService.deleteStudent(studentId);
}
}
5. 訪問(wèn)地址 http://localhost:8080/swagger-ui/



6. swagger 常用注解
@Api:用在請(qǐng)求的類(lèi)上,表示對(duì)類(lèi)的說(shuō)明
tags="說(shuō)明該類(lèi)的作用,可以在UI界面上看到的注解"
value="該參數(shù)沒(méi)什么意義,在UI界面上也看到,所以不需要配置"
@ApiOperation:用在請(qǐng)求的方法上,說(shuō)明方法的用途、作用
value="說(shuō)明方法的用途、作用"
notes="方法的備注說(shuō)明"
@ApiImplicitParams:用在請(qǐng)求的方法上,表示一組參數(shù)說(shuō)明
@ApiImplicitParam:用在@ApiImplicitParams注解中,指定一個(gè)請(qǐng)求參數(shù)的各個(gè)方面
name:參數(shù)名
value:參數(shù)的漢字說(shuō)明、解釋
required:參數(shù)是否必須傳
paramType:參數(shù)放在哪個(gè)地方
· header --> 請(qǐng)求參數(shù)的獲?。篅RequestHeader
· query --> 請(qǐng)求參數(shù)的獲?。篅RequestParam
· path(用于restful接口)--> 請(qǐng)求參數(shù)的獲?。篅PathVariable
· body(不常用)
· form(不常用)
dataType:參數(shù)類(lèi)型,默認(rèn)String,其它值dataType="Integer"
defaultValue:參數(shù)的默認(rèn)值
@ApiResponses:用在請(qǐng)求的方法上,表示一組響應(yīng)
@ApiResponse:用在@ApiResponses中,一般用于表達(dá)一個(gè)錯(cuò)誤的響應(yīng)信息
code:數(shù)字,例如400
message:信息,例如"請(qǐng)求參數(shù)沒(méi)填好"
response:拋出異常的類(lèi)
@ApiModel:用于響應(yīng)類(lèi)上,表示一個(gè)返回響應(yīng)數(shù)據(jù)的信息
(這種一般用在post創(chuàng)建的時(shí)候,使用@RequestBody這樣的場(chǎng)景,
請(qǐng)求參數(shù)無(wú)法使用@ApiImplicitParam注解進(jìn)行描述的時(shí)候)
@ApiModelProperty:用在屬性上,描述響應(yīng)類(lèi)的屬性
