springboot项目引入Swagger2步骤

第一步：增长jar包，引入最新版本2.9.2，访问的时候会报错java.lang.NumberFormatException，排除报错的包能够解决、也能够引入旧的jar包

<!-- 添加Swagger2依赖,用于生成接口文档 -->
        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger2</artifactId>
            <version>2.9.2</version>
            <!-- 报错信息：java.lang.NumberFormatException: For input string: “” 排除jar包引用旧的jar包解决问题 -->
            <exclusions>
                <exclusion>
                    <groupId>io.swagger</groupId>
                    <artifactId>swagger-annotations</artifactId>
                </exclusion>
                <exclusion>
                    <groupId>io.swagger</groupId>
                    <artifactId>swagger-models</artifactId>
                </exclusion>
            </exclusions>
        </dependency>

        <!-- 引用旧的jar 排除新jar包中的问题 start -->
        <dependency>
            <groupId>io.swagger</groupId>
            <artifactId>swagger-annotations</artifactId>
            <version>1.5.21</version>
        </dependency>
        <dependency>
            <groupId>io.swagger</groupId>
            <artifactId>swagger-models</artifactId>
            <version>1.5.21</version>
        </dependency>

        <dependency>
            <groupId>io.springfox</groupId>
            <artifactId>springfox-swagger-ui</artifactId>
            <version>2.9.2</version>
        </dependency>

引入旧jar包

<!-- 添加Swagger2依赖,用于生成接口文档 -->
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger2</artifactId>
        <version>2.7.0</version>
    </dependency>
    <dependency>
        <groupId>io.springfox</groupId>
        <artifactId>springfox-swagger-ui</artifactId>
        <version>2.7.0</version>
    </dependency>
    <!--end-->

第二步：配置Configuration配置

@Configuration
@EnableSwagger2
public class Swagger2Configuration {
    //api接口包扫描路径
    public static final String SWAGGER_SCAN_BASE_PACKAGE = "com.cn.auth.controller.census";
    public static final String VERSION = "1.0.0";

    @Bean
    public Docket createRestApi() {
        return new Docket(DocumentationType.SWAGGER_2)
                .apiInfo(apiInfo())
                .select()
                .apis(RequestHandlerSelectors.basePackage(SWAGGER_SCAN_BASE_PACKAGE))
                .paths(PathSelectors.any()) // 能够根据url路径设置哪些请求加入文档，忽略哪些请求
                .build();
    }

    private ApiInfo apiInfo() {
        return new ApiInfoBuilder()
                .title("权限管理系统") //设置文档的标题
                .description("权限管理系统API接口文档") //设置文档的描述
                .version(VERSION) //设置文档的版本信息
                .termsOfServiceUrl("localhost:8088") // 设置文档的License信息
                .build();
    }
}

第三步：配置shiro权限过滤

filterChainDefinitionMap.put("/swagger-ui.html","anon");
 filterChainDefinitionMap.put("/v2/*","anon");
 filterChainDefinitionMap.put("/swagger-resources/**","anon");

第四步：方法描述示例

@Api(description = "示例文档API接口")
@RestController
@RequestMapping("/swagger_example")
public class SwaggerExample {
    @RequestMapping(value ="getTableList",method=RequestMethod.POST)
    @ApiOperation(value="获取数据库表的列表")
    @ApiImplicitParams({
            @ApiImplicitParam(name="tableName",value="数据库表名",required=false,paramType="form",dataType="String"),
            @ApiImplicitParam(name="page",value="第几页",required=true,paramType="form",dataType="int"),
            @ApiImplicitParam(name="floatExp",value="传float类型数据",required=false,paramType="form",dataType="float"),
            @ApiImplicitParam(name="doubleExp",value="传double类型数据",required=false,paramType="form",dataType="double"),
            @ApiImplicitParam(name="booleanExp",value="传boolean类型数据",required=false,paramType="form",dataType="boolean"),
            @ApiImplicitParam(name="limit",value="每页多少条数据",required=true,paramType="form",dataType="int")})
 public BasePageData getTableList(String tableName, Integer page, Integer limit) {
        BasePageData data = new BasePageData();
        data.setMsg("操做成功");
        return data;
    }
}

第四步：请求地址出现接口页面
http://localhost:8088/swagger-ui.html
