LogViewer can be added to existing Spring Boot application as a library. The library provides the log-viewer servlet. You can map the servlet to any URL and it will show logs. Log configuration will be detected automatically.

The library is io.github.sevdokimov.logviewer:log-viewer-spring-boot:1.0.10

Maven configuration

<dependencies>
    <dependency>
        <groupId>io.github.sevdokimov.logviewer</groupId>
        <artifactId>log-viewer-spring-boot</artifactId>
        <version>1.0.10</version>
    </dependency>
</dependencies>

Gradle configuration

dependencies {
    implementation 'io.github.sevdokimov.logviewer:log-viewer-spring-boot:1.0.10'
}

When the log-viewer library is added, add com.logviewer.springboot.LogViewerSpringBootConfig configuration class to the Spring configuration.
That's all! LogViewerSpringBootConfig maps LogViewerServlet servlet to "/logs" URL, list of log files and its format will be detected automatically.

URL for LogViewerServlet servlet mapping can be specified by log-viewer.url-mapping property.

You can specify the list of available logs manually, if LogViewer cannot detect it automatically. Create a spring bean of type com.logviewer.logLibs.LogConfigurationLoader that has Map<Path, LogFormat> getLogConfigurations() method. This method returns a map containing paths to log files mapped to formats. The format may be "null", in this case LogViewer will detect the format automatically. The default log configuration detection can be disabled by log-viewer.disable-default-configuration-loader=true property.

If your application support WebSocket, add com.logviewer.springboot.LogViewerWebsocketConfig configuration class too. It switches UI ⟷ Backend interaction to WebSocket protocol. WebSocket works slightly faster than HTTP requests.
Path for WebSocket endpoint can be specified by log-viewer.websocket.path property.
