paths = /html/body/div/div[3]/div/div/div[1]/div/ul[1]/li[1]/a 可以吗可以遍历出path吗

可以，这个 XPath 表达式表示的是 HTML 文档中的一组嵌套元素，可以通过这个 XPath 表达式遍历出这组元素的路径。具体来说，这个 XPath 表达式表示的是：

- `html` 元素下的 `body` 元素
- `body` 元素下的第三个 `div` 元素
- 第三个 `div` 元素下的第一个 `div` 元素
- 第一个 `div` 元素下的第一个 `ul` 元素
- 第一个 `ul` 元素下的第一个 `li` 元素
- 第一个 `li` 元素下的第一个 `a` 元素

因此，如果你想要遍历出这个 XPath 表达式所表示的元素路径，可以按照上面的顺序遍历 HTML 文档中的元素，并记录每个元素的名称和索引号。例如，这个 XPath 表达式表示的元素路径为：

html -> body[1] -> div[3] -> div[1] -> ul[1] -> li[1] -> a[1]

No mapping for GET /swagger-ui.html

您在访问`/swagger-ui.html`时出现了`No mapping for GET`错误。这个错误通常是由于您的应用程序缺少相应的请求映射所引起的。

要解决这个问题，您可以尝试以下几个步骤：

1. 确保您的应用程序中已经正确配置了Swagger相关的依赖项。您可以在`pom.xml`文件中添加以下依赖项：

<dependency>
    <groupId>io.springfox</groupId>
    <artifactId>springfox-swagger2</artifactId>
    <version>2.9.2</version>
</dependency>

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

或者，如果您使用Gradle构建工具，则可以在`build.gradle`文件中添加以下依赖项：

implementation 'io.springfox:springfox-swagger2:2.9.2'
implementation 'io.springfox:springfox-swagger-ui:2.9.2'

2. 确保您的应用程序中已经正确配置了Swagger的相关配置类。您可以创建一个继承自`WebMvcConfigurationSupport`的配置类，并重写`addResourceHandlers`方法，将Swagger的资源路径添加到资源处理程序中。例如：

@Configuration
@EnableSwagger2
public class SwaggerConfig extends WebMvcConfigurationSupport {

    @Override
    protected void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("swagger-ui.html")
                .addResourceLocations("classpath:/META-INF/resources/");

        registry.addResourceHandler("/webjars/**")
                .addResourceLocations("classpath:/META-INF/resources/webjars/");
    }
}

3. 确保您的应用程序中已经正确配置了Swagger的API文档。您可以创建一个Swagger配置类，并使用`@Api`和`@ApiOperation`等注解来定义API接口和操作。例如：

@Configuration
@EnableSwagger2
public class SwaggerConfig {

    @Bean
    public Docket api() {
        return new Docket(DocumentationType.SWAGGER_2)
                .select()
                .apis(RequestHandlerSelectors.basePackage("com.example.controller"))
                .paths(PathSelectors.any())
                .build();
    }
}

请根据您的具体情况检查以上步骤，并确保正确配置了Swagger相关的依赖项、配置类和API文档。如果问题仍然存在，请提供更多详细信息以便我能够更好地帮助您解决问题。

dlopen /usr/lib/librga.so failed

The error message "dlopen /usr/lib/librga.so failed" indicates that the dynamic linker `dlopen` failed to load the shared library `librga.so` located in the `/usr/lib` directory. This error can occur due to various reasons, such as missing library dependencies, incorrect library paths, or insufficient permissions.

Here are some steps you can try to resolve this issue:

1. Verify if the `librga.so` library file exists in the `/usr/lib` directory. You can use the `ls` command to check its presence:

   ls /usr/lib/librga.so

2. If the file exists, ensure that the library has the correct permissions for the user running the application. You can use the `chmod` command to set the appropriate permissions:

   sudo chmod 755 /usr/lib/librga.so

3. Check if there are any missing dependencies required by `librga.so`. You can use the `ldd` command to identify the dependencies:

   ldd /usr/lib/librga.so

Make sure all the listed dependencies are present and properly installed on your system.

4. If the library depends on other shared libraries, you might need to update the library search path to include the directory where those dependencies are located. You can set the `LD_LIBRARY_PATH` environment variable to include the necessary paths:

   export LD_LIBRARY_PATH=/path/to/dependencies:$LD_LIBRARY_PATH

Replace `/path/to/dependencies` with the actual directory path containing the dependencies.

5. If the issue persists, it's possible that there is a problem with the library itself. In such cases, you may need to reinstall or obtain a proper version of the library from a reliable source.

If none of the above solutions work or if you need further assistance, please provide more details about your system, the software or application you are using, and any additional error messages you encounter.
