Springboot整合swagger，感觉网上很多有问题，最后总结出来的

依赖：

 <!--swaggers2-->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.6.1</version>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.6.1</version>
        </dependency>

配置文件：需要和启动类同一目录下。

package com.system.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2).apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.system.controller"))
                .paths(PathSelectors.any()).build();
    }


    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("Spring Boot中使用Swagger2构建RESTful APIs")
                .description("myapp")
                .termsOfServiceUrl("http://blog.csdn.net/java_yes")
                .version("1.0").build();
    }
}

controller：

@Api(tags = "StatisticController", description = "报表")
public class StatisticController {
    @Autowired
    private DeptService deptService;
    @Autowired
    private BuildService buildService;
    @Autowired
    private EventProcessService eventProcessService;
    @Autowired
    private StatisticService statisticService;
    @Autowired
    private CampusService campusService;
    //工资统计报表
    @ApiOperation(value="工资统计报表", notes="")
    @ApiImplicitParam(name = "user", value = "用户详细实体user", required = true, dataType = "User")
    @GetMapping(value = "getSalary")
    @ResponseBody
    public List<EchartCommonVo> getSalary(Integer campusid, Integer deptid){
        Integer whweight=3;
        Integer jbweight=7;
        User loginuser= (User) SecurityUtils.getSubject().getSession().getAttribute("loginuser");
        DateTimeFormatter df = DateTimeFormatter.ofPattern("yyyy-MM-dd HH:mm:ss");
        LocalDateTime today=LocalDateTime.now();
        LocalDateTime AMouthBefore = today.minusMonths(1);
        LocalDateTime now = today.with(today);
        String start = df.format(AMouthBefore);
        String end=df.format(now);
        User user= (User) SecurityUtils.getSubject().getSession().getAttribute("loginuser");
        List<Dept> selectdepts=eventProcessService.getDeptBySelect(loginuser);
        List<WorkLoadInfo> workLoadInfos=statisticService.getSalary(AMouthBefore,now,AMouthBefore,now,"1",whweight,jbweight,10);
        List<EchartCommonVo> echartCommonVos=new ArrayList<EchartCommonVo>();
        for(WorkLoadInfo vo:workLoadInfos){
            EchartCommonVo evo=new EchartCommonVo(vo.getRealname(),vo.getResult().toString());
            echartCommonVos.add(evo);
        }
        return echartCommonVos;
    }

多参数：

 @ApiImplicitParams({
            @ApiImplicitParam(name = "file", value = "上传图片", required = true, dataType = "MultipartFile"),
            @ApiImplicitParam(name = "location", value = "暂时不知道什么用", required = true, dataType = "Integer")
    })

实体类:(实体类即使没有写注解，显示都一样，所以暂时不知道有什么用)

import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
 
@ApiModel(value = "用户实体类")
public class User {
 
    @ApiModelProperty(value = "用户唯一标识")
    private Long id;
 
    @ApiModelProperty(value = "用户姓名")
    private String username;
 
    @ApiModelProperty(value = "用户密码")
    private String password;
 
    // 省略set和get方法
}
