support for java.text.MessageFormat style formatting in SLF4J
by Ceki Gulcu 16 Oct '15

16 Oct '15

Hi all, Over the years there have been several requests by users to support java.text.MessageFormat style formatting in SLF4J. Currently, SLF4J only supports its own style using accolades, as in logger.info("User {} has logged on", userName); whereas the java.text.MessageFormat style is more sophisticated. Here are two examples of logger calls using java.text.MessageFormat style logger.info("User {1} has logged on", userName); logger.info("Current temperature is {1, number, #.##} degrees", t); SLF4J API does not support java.text.MessageFormat style because a significant proportion of projects using slf4j depend on external software. If two software components use different formatting styles for logging, then if any which one of the supported styles is chosen by the user via some configuration option, then logging statements based on the other style (the one not chosen by the user) will render as gibberish. There is no way to get around this problem with a *global* configuration switch. A slightly different approach would be to apply one style on a subset of the logger statements in the project and apply another style on the rest. However, this would come at some computational cost and more importantly a high configuration cost paid by the unsuspecting end-user. In my opinion, a better approach is to support both styles simultaneously. Looking at the message, it is easy to tell which style is desired by the user. For example, "Hello world" // unparameterized "User {} has logged on" // slf4j-style "User {1} has logged on" // j.t.M style "Current temperature is {1, number, #.##} degrees" // j.t.M style Coding the method returning the desired formatting style by logging at some string should not be hard. The only difficulty is doing so efficiently and at a very small computational cost. Anyone interested in tackling this problem? -- Ceki
