java集成Swagger的步骤详解

Swagger集成很simple，并不需要向网上说的那么复杂

添加pom 文件

        <dependency>
            <groupId>com.fasterxml.jackson.coregroupId>
            <artifactId>jackson-annotationsartifactId>
            <version>2.8.3version>
        dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.coregroupId>
            <artifactId>jackson-databindartifactId>
            <version>2.8.3version>
        dependency>

        <dependency>
            <groupId>io.springfoxgroupId>
            <artifactId>springfox-swagger2artifactId>
            <version>2.6.1version>
        dependency>
        <dependency>
            <groupId>io.springfoxgroupId>
            <artifactId>springfox-swagger-uiartifactId>
            <version>2.6.1version>
        dependency>

新建controller

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurationSupport;
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
@EnableWebMvc
@EnableSwagger2
public class Swagger2 extends WebMvcConfigurationSupport
{

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

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("测试页面")
                .termsOfServiceUrl("localhost:8080")
                .contact("ROY")
                .version("1.1")
                .build();
    }
}

spring mvc

 <mvc:resources location="classpath:/META-INF/resources/" mapping="swagger-ui.html"/>
 <mvc:resources location="classpath:/META-INF/resources/webjars/" mapping="/webjars/**"/>

启动服务，然后在浏览器输入

http://ip:port/swagger-ui.html

完成了
