Package org.thymeleaf.spring4.dialect

Class SpringStandardDialect

  • All Implemented Interfaces:
    org.thymeleaf.dialect.IDialect, org.thymeleaf.dialect.IExecutionAttributeDialect, org.thymeleaf.dialect.IExpressionObjectDialect, org.thymeleaf.dialect.IProcessorDialect
    public class SpringStandardDialect
extends org.thymeleaf.standard.StandardDialect

    SpringStandard Dialect. This is the class containing the implementation of Thymeleaf Standard Dialect, including all th:* processors, expression objects, etc. for Spring-enabled environments.

    Note this dialect uses SpringEL as an expression language and adds some Spring-specific features on top of StandardDialect, like th:field or Spring-related expression objects.

    The usual and recommended way of using this dialect is by instancing SpringTemplateEngine instead of TemplateEngine. The former will automatically add this dialect and perform some specific configuration like e.g. Spring-integrated message resolution.

    Note a class with this name existed since 1.0, but it was completely reimplemented in Thymeleaf 3.0

      • getEnableSpringELCompiler

        public boolean getEnableSpringELCompiler()

        Returns whether the SpringEL compiler should be enabled in SpringEL expressions or not.

        Expression compilation can significantly improve the performance of Spring EL expressions, but might not be adequate for every environment. Read the official Spring documentation for more detail.

        Also note that although Spring includes a SpEL compiler since Spring 4.1, most expressions in Thymeleaf templates will only be able to properly benefit from this compilation step when at least Spring Framework version 4.2.4 is used.

        This flag is set to false by default.

        Returns:
        true if SpEL expressions should be compiled if possible, false if not.

      • setEnableSpringELCompiler

        public void setEnableSpringELCompiler​(boolean enableSpringELCompiler)

        Sets whether the SpringEL compiler should be enabled in SpringEL expressions or not.

        Expression compilation can significantly improve the performance of Spring EL expressions, but might not be adequate for every environment. Read the official Spring documentation for more detail.

        Also note that although Spring includes a SpEL compiler since Spring 4.1, most expressions in Thymeleaf templates will only be able to properly benefit from this compilation step when at least Spring Framework version 4.2.4 is used.

        This flag is set to false by default.

        Parameters:
        enableSpringELCompiler - true if SpEL expressions should be compiled if possible, false if not.

      • getRenderHiddenMarkersBeforeCheckboxes

        public boolean getRenderHiddenMarkersBeforeCheckboxes()

        Returns whether the <input type="hidden" ...> marker tags rendered to signal the presence of checkboxes in forms when unchecked should be rendered before the checkbox tag itself, or after (default).

        A number of CSS frameworks and style guides assume that the <label ...> for a checkbox will appear in markup just after the <input type="checkbox" ...> tag itself, and so the default behaviour of rendering an <input type="hidden" ...> after the checkbox can lead to bad application of styles. By tuning this flag, developers can modify this behaviour and make the hidden tag appear before the checkbox (and thus allow the lable to truly appear right after the checkbox).

        Note this hidden field is introduced in order to signal the existence of the field in the form being sent, even if the checkbox is unchecked (no URL parameter is added for unchecked check boxes).

        This flag is set to false by default.

        Returns:
        true if hidden markers should be rendered before the checkboxes, false if not.
