JAVA项目关于Knife4j接口工具的引用

1、添加pom引用。

<!-- swagger3-->
        <dependency>
            <groupId>com.github.xiaoymin</groupId>
            <artifactId>knife4j-spring-boot-starter</artifactId>
            <version>3.0.2</version>
        </dependency>

2、配置application.yml文件。

# knife4j配置
knife4j:
  enable: true
  setting:
    enableDocumentManage: false
    enableSwaggerModels: false
    enableSearch: false
    enableOpenApi: false
    enableVersion: false
    enableAfterScript: false
    enableFooter: false
    enableFooterCustom: true
    footerCustomContent: Copyright
    enableHomeCustom: false
    homeCustomLocation: classpath:markdown/home.md
    enableDynamicParameter: false
    enableHost: false
    enableHostText: localhost:8000
    enableDebug: true
    enableGroup: true

3、创建Knife4jConfiguration配置类。

package com.test.web.core.config;

import com.github.xiaoymin.knife4j.spring.annotations.EnableKnife4j;
import com.github.xiaoymin.knife4j.spring.extension.OpenApiExtensionResolver;
import io.swagger.annotations.ApiOperation;
import org.springframework.beans.factory.annotation.Autowired;
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.spi.DocumentationType;
import springfox.documentation.spring.web.plugins.Docket;

/**
 * @ClassName Knife4jConfiguration
 * @Description 
 * @Author 
 * @Date 
 * @Version 1.0
 **/
@Configuration
@EnableKnife4j
public class Knife4jConfiguration {
    /*引入Knife4j提供的扩展类*/
    private final OpenApiExtensionResolver openApiExtensionResolver;

    @Autowired
    public Knife4jConfiguration(OpenApiExtensionResolver openApiExtensionResolver) {
        this.openApiExtensionResolver = openApiExtensionResolver;
    }
    @Bean(value = "OnLine")
    public Docket defaultApi2() {
        Docket docket=new Docket(DocumentationType.OAS_30)
                .apiInfo(new ApiInfoBuilder()
                        .title("在线调用测试")
                        .description("在线调用测试Swagger升级Knife4j工具")
                        .version("1.0")
                        .build()
                        )
                //分组名称
                .select()
                //这里指定Controller扫描包路径
                .apis(RequestHandlerSelectors.withMethodAnnotation(ApiOperation.class))
                .paths(PathSelectors.any())
                .build()
                .extensions(openApiExtensionResolver.buildExtensions("2.X"));
        return docket;
    }
}

4、创建测试接口。

package com.test.web.controller.tool;

import java.util.ArrayList;
import java.util.LinkedHashMap;
import java.util.List;
import java.util.Map;
import org.springframework.web.bind.annotation.DeleteMapping;

import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.PostMapping;
import org.springframework.web.bind.annotation.PutMapping;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;
import com.test.common.core.controller.BaseController;
import com.test.common.core.domain.AjaxResult;
import com.test.common.utils.StringUtils;
import io.swagger.annotations.Api;
import io.swagger.annotations.ApiImplicitParam;
import io.swagger.annotations.ApiImplicitParams;
import io.swagger.annotations.ApiModel;
import io.swagger.annotations.ApiModelProperty;
import io.swagger.annotations.ApiOperation;

/**

        users.put(1, new UserEntity(1, "admin", "admin", "11111111111"));
        users.put(2, new UserEntity(2, "test", "test", "22222222222"));
    }

    @ApiOperation("获取用户列表")
    @GetMapping("/list")

        return AjaxResult.success(userList);
    }

    @ApiOperation("获取用户详细")
    @ApiImplicitParam(name = "userId", value = "用户ID", required = true, dataType = "int", paramType = "path")
    @GetMapping("/{userId}")
    public AjaxResult getUser(@PathVariable Integer userId)
    {
        if (!users.isEmpty() && users.containsKey(userId))
        {
            return AjaxResult.success(users.get(userId));
        }
        else

    })
    @PostMapping("/save")
    public AjaxResult save(UserEntity user)
    {
        if (StringUtils.isNull(user) || StringUtils.isNull(user.getUserId()))
        {
            return error("用户ID不能为空");
        }
        return AjaxResult.success(users.put(user.getUserId(), user));
    }

    @ApiOperation("更新用户")
    @PutMapping("/update")
    public AjaxResult update(@RequestBody UserEntity user)
    {
        if (StringUtils.isNull(user) || StringUtils.isNull(user.getUserId()))
        {
            return error("用户ID不能为空");
        }
        if (users.isEmpty() || !users.containsKey(user.getUserId()))
        {

        }
        users.remove(user.getUserId());
        return AjaxResult.success(users.put(user.getUserId(), user));
    }

    @ApiOperation("删除用户信息")
    @ApiImplicitParam(name = "userId", value = "用户ID", required = true, dataType = "int", paramType = "path")
    @DeleteMapping("/{userId}")
    public AjaxResult delete(@PathVariable Integer userId)
    {
        if (!users.isEmpty() && users.containsKey(userId))
        {
            users.remove(userId);
            return success();
        }
        else
        {
            return error("用户不存在");
        }
    }
}

@ApiModel(value = "UserEntity", description = "用户实体")
class UserEntity
{
    @ApiModelProperty("用户ID")
    private Integer userId;

    @ApiModelProperty("用户名称")
    private String username;

    @ApiModelProperty("用户密码")
    private String password;

    @ApiModelProperty("用户手机")
    private String mobile;

    public UserEntity()
    {

    }

    public UserEntity(Integer userId, String username, String password, String mobile)
    {
        this.userId = userId;
        this.username = username;
        this.password = password;

    }

    public Integer getUserId()
