swagger 报错 Ambiguous handler methods mapped for ‘/v3/api-docs/‘

在启动项目A时, 调用/v3/api-docs 接口 发现报错 返回值

{"errorCode":"Unknown","code":500,"path":"/v3/api-docs/","stack":"","errorMsg":"Ambiguous handler methods mapped for '/v3/api-docs/': {public java.lang.String org.springdoc.api.OpenApiResource.openapiJson(javax.servlet.http.HttpServletRequest,java.lang.String) throws com.fasterxml.jackson.core.JsonProcessingException, public org.springframework.http.ResponseEntity springfox.documentation.oas.web.OpenApiControllerWebMvc.getDocumentation(java.lang.String,javax.servlet.http.HttpServletRequest)}"}

 

使用maven命令" mvn dependency:tree "排查, 发现是swagger的jar包冲突, 因为A依赖了B

项目A

        <dependency>
            <groupId>org.springdoc</groupId>
            <artifactId>springdoc-openapi-core</artifactId>
            <version>1.1.49</version>
        </dependency>

项目B

            <dependency>
                <groupId>io.springfox</groupId>
                <artifactId>springfox-boot-starter</artifactId>
                <version>3.0.0</version>
            </dependency>

最终排除掉B项目中的依赖, 接口恢复正常

            <dependency>
                <groupId>com.xxx.xxx</groupId>
                <artifactId>project-B</artifactId>
                <version>1.0</version>
                <exclusions>
                    <exclusion>
                        <groupId>io.springfox</groupId>
                        <artifactId>springfox-boot-starter</artifactId>
                    </exclusion>
                </exclusions>
            </dependency>

另外有遇到提示报错

nested exception is java.lang.NoClassDefFoundError: org/apache/ibatis/type/JdbcType

导入jar包就正常了

<dependency>
    <groupId>org.mybatis</groupId>
    <artifactId>mybatis</artifactId>
    <version>3.5.5</version>
</dependency>
