[logback-dev] [JIRA] (LOGBACK-1101) Unable to set string properties to json strings with nested nodes

[Phil (JIRA)]

Phil created LOGBACK-1101 Unable to set string properties to json strings with nested nodes Issue Type: Bug Affects Versions: 1.1.3 Assignee: Logback dev list Attachments: logback-substitution-bug.zip Components: logback-core Created: 17/Sep/15 7:22 AM Description: I have an appender that has a string property. I would like that property to be in a JSON string format. However, due to a parsing logic error, logback's variable substitution logic for strings will remove the last right curly brace from the string. This prevents me from being able to use a JSON string property. For example, if the logback.xml contains: <appender name="xxx" class="TestAppender"> <testProperty>{"hello":{"world":"yay"}}</testProperty> </appender> And the TestAppender class contains: public void setTestProperty(String testProperty) { //... } I expect logback to pass the following string to the setTestProperty method: {"hello":{"world":"yay"}} However, logback incorrectly strips off the trailing right curly brace, and instead passes the following string {"hello":{"world":"yay"} I have attached a project that demonstrates the behavior. To run the test, execute the following: mvn clean package java -cp target/substitution-test-1.0-SNAPSHOT.jar Main Project: logback Priority: Major Reporter: Phil
