springboot-集成swaggerui

1. 添加依赖

<dependency>
    <groupId>io.springfoxgroupId>
    <artifactId>springfox-swagger2artifactId>
    <version>2.7.0version>
dependency>
<dependency>
    <groupId>io.springfoxgroupId>
    <artifactId>springfox-swagger-uiartifactId>
    <version>2.7.0version>
dependency>

 

2.Swagger配置

package com.gary.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import springfox.documentation.builders.ApiInfoBuilder;
import springfox.documentation.builders.ParameterBuilder;
import springfox.documentation.builders.PathSelectors;
import springfox.documentation.builders.RequestHandlerSelectors;
import springfox.documentation.schema.ModelRef;
import springfox.documentation.service.ApiInfo;
import springfox.documentation.service.Contact;
import springfox.documentation.service.Parameter;
import springfox.documentation.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;
import springfox.documentation.swagger2.annotations.EnableSwagger2;
import java.util.ArrayList;
import java.util.List;

@Configuration
@EnableSwagger2
public class SwaggerConfig {
    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .useDefaultResponseMessages(false)
                .globalOperationParameters(globalOperationParameters())// 全局参数
                .select()
                .apis(RequestHandlerSelectors.any())
                .paths(PathSelectors.regex("/.*"))// 监控所有路径
                .build();
    }
    private List globalOperationParameters(){
        ParameterBuilder builder = new ParameterBuilder();
        Parameter parameter = builder.name("token").description("登录接口返回的token")
                .modelRef(new ModelRef("string"))
                .parameterType("header")
                .required(false).build();
        ArrayList parameters = new ArrayList<>();
        parameters.add(parameter);
        return parameters;
    }
    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("测试API文档")
                .description("格伦发展有限公司 Copyright 2000-2030 (C) All Rights Reserved.")
                .termsOfServiceUrl("http://www.gary.cn/")
                .contact(new Contact("gary",null,"[email protected]"))
                .version("1.0")
                .build();
    }
}

 

3.Controller类添加说明

package com.controller;

import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiOperation;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;

import javax.servlet.http.HttpServletRequest;

@Controller
@Api(description = "登录/注销接口")
public class ThemeleafController {
    @ApiOperation(value = "跳转登录页面")
    @GetMapping("/toLogin")
    public String toLogin(){
        return "user/login";
    }

    @ApiOperation(value = "查询用户接口")
    @ApiImplicitParams({ @ApiImplicitParam(name = "address", value = "地址", paramType = "query", required = true),
            @ApiImplicitParam(name = "age", value = "年龄", paramType = "query", required = true)})
    @RequestMapping(value="/users",method = RequestMethod.GET)
    public Result.Base login(HttpServletRequest request, String address, String age){

        User user = User.builder().build();
        return new Result.Success<>(user);
    }

    @PostMapping("/doLogin")
    @ApiOperation(value = "登录接口")
    public String doLogin(@RequestBody LoginVo loginVo){
        System.out.println(loginVo.toString());
        return "home";
    }
}

 

实体类中：

@Data
@Builder
@ApiModel(description = "登录参数")
public class LoginVo {
    @ApiModelProperty(value = "用户名", required = false)
    private String username;
    @ApiModelProperty(value = "密码", required = false)
    private String password;
}

 

4.访问

http://localhost:8087/ swagger-ui.html

5.问题

访问页面时找不到页面，后台报：

No mapping for GET /swagger-ui.html

说明Spring Boot自动配置本身没有把/swagger-ui.html这个路径映射到对应的目录META-INF/resources/下面。添加配置类：

package com.wps.education.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
@Configuration
class WebMvcConfig extends WebMvcConfigurerAdapter {
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");

        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
}

或者在拦截器中直接添加：

package com.gary.interseptor;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import springfox.documentation.swagger2.annotations.EnableSwagger2;

@Configuration
@EnableWebMvc
@EnableSwagger2
public class MyWebMvcConfigurerAdapter extends WebMvcConfigurerAdapter{
    /**
     * 拦截器
     * @param registry
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        // addPathPatterns 用于添加拦截规则
        // excludePathPatterns 用户排除拦截
        registry.addInterceptor(new LoginInterceptor())
                .addPathPatterns("/**")
                .excludePathPatterns("/toLogin","/doLogin",
                        "/swagger-resources/**", "/v2/**", "/static/**","/error/**",
                        "/webjars/**", "/swagger-ui.html/**","/swagger-resources/**");
        super.addInterceptors(registry);
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");
        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
}
