SpringBoot3.1.2 引入Swagger报错Type javax.servlet.http.HttpServletRequest not present解决办法
作者：liyinchi1988
这篇文章主要介绍了SpringBoot3.1.2 引入Swagger报错Type javax.servlet.http.HttpServletRequest not present解决办法,文中通过代码示例给大家介绍的非常详细,需要的朋友可以参考下
1.问题描述：
引入swagger2.X版本后，导致SpringBoot3.1.2启动报错
2.原因分析：
SpringBoot3.1.2版本依赖于jakarta依赖包，但是Swagger依赖底层应用的javax依赖包，所以只要一启动就会报错。
3.解决办法：
pom.xml文件，移除swagger2
<dependency>
<groupId>io.springfox</groupId>
<artifactId>springfox-swagger2</artifactId>
<version>2.9.2</version>
</dependency>
<dependency>
<groupId>com.github.xiaoymin</groupId>
<artifactId>swagger-bootstrap-ui</artifactId>
<version>1.9.0</version>
<scope>provided</scope>
</dependency>加入
<dependency>
<groupId>io.swagger.core.v3</groupId>
<artifactId>swagger-annotations</artifactId>
<version>2.2.15</version>
</dependency>
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-starter-webmvc-ui</artifactId>
<version>2.1.0</version>
</dependency>代码修改
@Api(tags = "") 改为 @Tag(name = "") @ApiModel(value="", description="") 改为 @Schema(name="", description="") @ApiModelProperty(value = "", required = true) 改为 @Schema(name= "", description = "", required = true) @ApiOperation(value = "", notes = "") 改为 @Operation(summary = "", description = "") @ApiParam 改为 @Parameter @ApiResponse(code = 404, message = "") 改为 @ApiResponse(responseCode = "404", description = "")

}遇到报错：
java.lang.StringIndexOutOfBoundsException: begin 11, end 10, length 10
原因分析：
由于Springdoc OpenAPI UI的版本与Spring Boot的版本不兼容导致的。你正在使用的Springdoc OpenAPI UI的版本是2.1.0，而Spring Boot的版本是3.1.2。这两个版本可能存在不兼容的问题。
解决办法：
你可以尝试将Springdoc OpenAPI UI的版本升级到与Spring Boot 3.1.2更兼容的版本。你可以在Springdoc的GitHub仓库的release页面查看各个版本的发布说明，找到一个与Spring Boot 3.1.2兼容的版本。
然后，你可以在你的pom.xml文件中更新Springdoc OpenAPI UI的版本：
<dependency>
<groupId>org.springdoc</groupId>
<artifactId>springdoc-openapi-ui</artifactId>
<version>新的版本号</version>
</dependency>https://github.com/springdoc/springdoc-openapi/releases
修改成支持springboot3.1.2的版本2.2.0后，成功~
