Log Capturing (with MongoDB + SpringBoot + Swagger UI)

This demo application showcases MongoDB and its capability to store data of varying schema.

Prerequisites

• Java and Maven
• A MongoDB server running locally on default port 27017

The data model

Each log event is represented as a key-value Map.

An example log might look like this:

{
  "logEvent": {
    "_id": "5f5542649469105a541140e1",
    "_appType": "PAYMENT",
    "_createDate": "2020-09-07T10:11:16.435",
    "severity": "ERROR",
    "creditCardProvider": "VISA",
    "message": "Payment failed",
    "paymentAmount": "9.90"
  }
}

REST Endpoints

Run the App

Go ahead and compile the source code. Then start the SpringBoot app LogCaptureApp. Now you're ready to fire REST requests on http://localhost:8080/swagger-ui.html.

Store logs:

• createLogRandom: Create a random log entry. You can choose the log source.
• createLog: Create a log entry from JSON. You can use any fields you want.

Display logs:

• getLogByApp: Search all log entries from a specific application of origin.
• getLogByDateRange: Search logs by time range.
• ... or use any other REST GET endpoint
