我如何更改此xml配置:
<bean id="templateEngine" class="org.thymeleaf.spring3.SpringTemplateEngine">
...
<property name="additionalDialects">
<set>
<bean class="org.thymeleaf.extras.springsecurity3.dialect.SpringSecurityDialect"/>
</set>
</property>
...
</bean>
到到目前为止的Java代码配置,我只有一个,在这一部分中我只有问题:
<property name="additionalDialects">
<set>
<bean class="org.thymeleaf.extras.springsecurity3.dialect.SpringSecurityDialect"/>
</set>
</property>
这是我到目前为止在Java代码中所拥有的:
@Bean
public SpringSecurityDialect springSecurityDialect() {
return new SpringSecurityDialect();
}
@Bean
public SpringTemplateEngine templateEngine() {
SpringTemplateEngine engine = new SpringTemplateEngine();
engine.setTemplateResolver( templateResolver() );
engine.setMessageSource( messageSource() );
//DIALECTS
Set<SpringSecurityDialect> ssdSet = new HashSet<SpringSecurityDialect>();
ssdSet.add( springSecurityDialect() );
engine.setAdditionalDialects( ssdSet ); <-- this line give me this error
return engine;
}
这行给我这个错误:
The method setAdditionalDialects(Set<IDialect>) in the type TemplateEngine is not applicable for the arguments (Set<SpringSecurityDialect>)
最佳答案
今天我用头撞了一下。答案在于查看Spring Boot源代码:
https://github.com/spring-projects/spring-boot/blob/v1.2.5.RELEASE/spring-boot-autoconfigure/src/main/java/org/springframework/boot/autoconfigure/thymeleaf/ThymeleafAutoConfiguration.java
@Configuration
@ConditionalOnClass({ SpringSecurityDialect.class })
protected static class ThymeleafSecurityDialectConfiguration {
@Bean
@ConditionalOnMissingBean
public SpringSecurityDialect securityDialect() {
return new SpringSecurityDialect();
}
}
因此,Spring Boot(好吧,“ org.springframework.boot:spring-boot-starter-thymeleaf”)将尝试注入org.thymeleaf.extras.springsecurity3.dialect.SpringSecurityDialect。也许它不起作用,因为我有springsecurity4 jar。
无论如何,有一个简单的解决方法:只需执行Spring Boot尝试执行的操作即可。在@Configuration类中,只需添加bean:
@Bean
public SpringSecurityDialect securityDialect() {
return new SpringSecurityDialect();
}
