spring boot项目运行问题

Question

我使用"spring tool suite“创建了spring boot starter项目。当我运行项目时，无法加载index.jsp页面。但是index.html可以很好地加载。

我的文件夹结构如下

​

​

我的家庭控制器是

package com.programmingfree.springservice;

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;

@Controller
public class HomeController {

    @RequestMapping("/")
    public String home() {
        return "index";
    }

}

如何运行index.jsp

Answer 1

您正在使用spring boot的默认配置，请看ThymeleafProperties.java，.html是后缀的默认设置：

@ConfigurationProperties(
    prefix = "spring.thymeleaf"
)
public class ThymeleafProperties {
    private static final Charset DEFAULT_ENCODING = Charset.forName("UTF-8");
    private static final MimeType DEFAULT_CONTENT_TYPE = MimeType.valueOf("text/html");
    public static final String DEFAULT_PREFIX = "classpath:/templates/";
    public static final String DEFAULT_SUFFIX = ".html";
    private boolean checkTemplate = true;
    private boolean checkTemplateLocation = true;
    private String prefix = "classpath:/templates/";
    private String suffix = ".html";
    private String mode = "HTML5";
    //......
}

所以你必须在application.properties中自定义你的配置：

spring.thymeleaf.prefix=classpath:/templates/  
spring.thymeleaf.suffix=.jsp

Answer 2

你在application.properties中有下一行吗？

spring.mvc.view.prefix: /WEB-INF/jsp/
spring.mvc.view.suffix: .jsp

由于为胸腺叶和FreeMarker自动配置的ResourceUrlEncodingFilter，到资源的链接在运行时会在模板中重写。在使用JSP时，您应该手动声明此过滤器。spring doc
