thymeleaf-spring5 ClassNotFoundException ognl/PropertyProcessor

See original GitHub issue

I tried to use thymeleaf in my project, but get the following exception: java.lang.NoClassDefFoundError: ognl/PropertyAccessor

My versions copied from mvn dependency:tree

org.thymeleaf:thymeleaf-spring5:jar:3.0.11.RELEASE:compile
  \- org.thymeleaf:thymeleaf:jar:3.0.11.RELEASE:compile
     +- org.attoparser:attoparser:jar:2.0.5.RELEASE:compile
     \- org.unbescape:unbescape:jar:1.1.6.RELEASE:compile

I think the issue here is that ognl is excluded by thymeleaf-spring5/pom.xml, see https://github.com/thymeleaf/thymeleaf-spring/blob/3.0-master/thymeleaf-spring5/pom.xml#L318

Unfortunately the relevant commits do not state why it was excluded, see b6a4911 and 896a147

I had the same issue as you, and adding this solve the problem for me:

        <dependency>
            <groupId>ognl</groupId>
            <artifactId>ognl</artifactId>
            <version>3.1.12</version>
        </dependency>

After lot of experimentation, following line makes the issue OGNL issue disappear for both Spring and Spring boot: TemplateEngine templateEngine = new SpringTemplateEngine();

Further, for spring boot to work properly, I had to configure engine as below: @Bean @Primary public TemplateEngine textTemplateEngine() { TemplateEngine templateEngine = new SpringTemplateEngine(); templateEngine.setTemplateResolver(templateResolver()); return templateEngine; }

As my use case is about simple string replacement in text templates, following is template resolver configuration: private ITemplateResolver templateResolver() { StringTemplateResolver templateResolver = new StringTemplateResolver(); templateResolver.setTemplateMode(TemplateMode.TEXT); return templateResolver; }
