Introduction

This is a Spring Boot Starter project which provides Rails like error pages for Spring Boot applications for development environments.

For rest requests, any error is archived until a configurable timeout and the error page url is sent in rest request’s response headers.

Demo

https://better-error-pages-demo.herokuapp.com

Note that demo page is a Heroku app so it may be sleeping when you first open the page, it may take 1-2 min for server to wake up.

Quick Start

Just add the dependency to your maven/gradle of your Spring Boot application then it will autoconfigure itself and Better Error Pages will be available if your active profiles includes dev or development.

Adding the dependency to your project

<dependencies>
  <dependency>
    <groupId>com.github.kodgemisi</groupId>
    <artifactId>better-error-pages-spring-boot-starter</artifactId>
    <version>${better-error-pages-spring-boot-starter.version}</version>
  </dependency>
</dependencies>

<repositories>
  <repository>
    <id>jitpack.io</id>
    <url>https://jitpack.io</url>
  </repository>
</repositories>

See https://jitpack.io/#kodgemisi/better-error-pages-spring-boot-starter for Jitpack usage, dependency details, version info and Gradle usage.

Configuration

Better Error Pages;

sets server.error.include-stacktrace: always and server.error.include-exception: true automatically.
autoconfigures itself if active profile has dev or development however you can override this via better-error-pages.profiles property.
finds your @SpringBootApplication annotated class and use its package name as better-error-pages.package-name name however you can override this via better-error-pages.package-name property.

Tip	Note that `package-name` should be typically your own base package which is used throughout your own classes like `com.yourcompany`.

better-error-pages:
  package-name: <String> # A package name whose classes' source code will be parsed and displayed in error pages.
  profiles: <String or List of string> # Override default profiles to enable Better Error Pages. Default value: "dev, development"

Important

Setting better-error-pages.package-name property improves startup performance significantly but won’t affect runtime performance.

Warning

If you set better-error-pages.package-name property then your project must have one of following files:

application.yml
application-dev.yml
application.properties
application-dev.properties

Limitations

Won’t work for package names containing upper case characters.
Can’t show source code in multi module projects only if the project is run as packaged but other features will work.
- When running multi module projects from an IDE everything just works.

Can't parse class name when package has underescore

When properties are given as:

Currently classNameRegexPattern is calculated as at ((com.kodgemisi.spotivote[a-z0-9\.]*)\.([A-Z]\w*)).*$(.+):(\d+)$ and it cannot parse following trace:

Also note that class names may also include underscore:

The "Java letters" include uppercase and lowercase ASCII Latin letters A-Z (\u0041-\u005a), and a-z (\u0061-\u007a), and, for historical reasons, the ASCII underscore (_, or \u005f) and dollar sign ($, or \u0024). The $ character should be used only in mechanically generated source code or, rarely, to access pre-existing names on legacy systems. [1]

Support source view when exception is caused from a spring proxy of a user class

Implementation notes:

There is no line number info in such trace
We may find the relevant line number via the method name but it doesn't seem very reliable
We can just load the whole java source file
example regex at (com\.example\.springcourse[a-z0-9\\.]*\.([A-Z]\w*))\$\$.*\.(\w+$.*$)
