[英]My project can't find jsp file, I think the problem is in application.properties file, but dont know how to fix it
我的项目找不到 jsp 文件。 我尝试在 application.properties 中添加这些行,但这不起作用
spring.view.prefix=/templates/
spring.view.suffix=.jsp
当我的 controller 返回 html 页面时一切正常,但这不适用于 jsp 这是我的应用程序。
spring.datasource.driverClassName=com.microsoft.sqlserver.jdbc.SQLServerDriver
spring.datasource.url=jdbc:sqlserver://localhost\\SQLEXPRESS:1433;databaseName=AdminToolWeb
spring.datasource.username=mssqllogin
spring.datasource.password=mssqllogin$
spring.jpa.show-sql=true
spring.jpa.properties.hibernate.format_sql = true
spring.view.prefix=/templates/
spring.view.suffix=.jsp
错误是

您似乎仍然使用 Thymeleaf 作为模板引擎。 要使用 JSP 模板,您需要添加tomcat-embed-japser
作为依赖项:
<dependency>
<groupId>org.apache.tomcat.embed</groupId>
<artifactId>tomcat-embed-jasper</artifactId>
<scope>provided</scope>
</dependency>
此外,我认为模板需要位于项目的src/main/webapp
文件夹中,而不是资源文件夹中。
正如@CostiCiudatu 提到的,属性必须是spring.mvc.view.prefix
和spring.mvc.view.suffix
(带有spring.mvc
前缀)。
您也可以通过在任何@Configuration
类中添加自定义视图解析器 bean 以编程方式进行此配置:
@Bean
public InternalResourceViewResolver viewResolver() {
final InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setPrefix("/templates/");
viewResolver.setSuffix(".jsp");
viewResolver.setViewClass(JstlView.class);
return viewResolver;
}
更新:
查看存储库后,发现您在 pom.xml 中仍然有 Thymeleaf 依赖项,因此在导致 Z2D7FCA4F5778E4B40B4606914719BB22 模板问题的类路径上。
I created a pull request that addresses this issue and configures your project as described in this answer https://stackoverflow.com/a/60213442/4323935 as you apparently want to use both JSP and Thymeleaf templates.
但是 - 除非有充分的理由使用多个模板引擎 - 我建议只坚持使用一个模板引擎。 Thymeleaf 是 Spring 引导的合理默认值,应该有充分的理由偏离此默认值。 使用多个模板引擎是一个非标准用例,将来可能会导致问题(例如,使用 Spring 更新等)
我想你忘记了.mvc.
部分,这些属性应该是:
spring.mvc.view.prefix = /templates/
spring.mvc.view.suffix = .jsp
