Java 8 Support Plugin
This plugin was dropped in Struts 2.5.5 as Struts Core is using ASM5 now which supports Java8.
Adds support for Java 8 - to allow use the latest features of the language with Struts actions.
You must define it as a dependency in
pom.xml and exclude the old version of ASM used with
xwork-core, see a code snippet below:
<dependency> <groupId>org.apache.struts.xwork</groupId> <artifactId>xwork-core</artifactId> <exclusions> <exclusion> <groupId>asm</groupId> <artifactId>asm</artifactId> </exclusion> <exclusion> <groupId>asm</groupId> <artifactId>asm-commons</artifactId> </exclusion> </exclusions> </dependency>
If you don’t use Maven to manage the dependencies, please be sure to replace
asm-commons.jar with appropriated ASM 5 versions.
Supported Java 8 features
- Lambda Expressions in actions when using them with the Convention plugin
