1.問(wèn)題描述：
引入swagger2.X版本后，導(dǎo)致SpringBoot3.1.2啟動(dòng)報(bào)錯(cuò)
2.原因分析：
SpringBoot3.1.2版本依賴于jakarta依賴包，但是Swagger依賴底層應(yīng)用的javax依賴包，所以只要一啟動(dòng)就會(huì)報(bào)錯(cuò)。
3.解決辦法：
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>

}遇到報(bào)錯(cuò)：
java.lang.StringIndexOutOfBoundsException: begin 11, end 10, length 10
原因分析：
由于Springdoc?OpenAPI?UI的版本與Spring?Boot的版本不兼容導(dǎo)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。這兩個(gè)版本可能存在不兼容的問(wèn)題。
解決辦法：
你可以嘗試將Springdoc?OpenAPI?UI的版本升級(jí)到與Spring?Boot?3.1.2更兼容的版本。你可以在Springdoc的GitHub倉(cāng)庫(kù)的release頁(yè)面查看各個(gè)版本的發(fā)布說(shuō)明，找到一個(gè)與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>新的版本號(hào)</version>
</dependency>https://github.com/springdoc/springdoc-openapi/releases
