java - Spring Boot在多模块项目中找不到jsp

标签 java spring spring-boot jsp http-status-code-404

我正在使用 spring boot，我决定只是为了将我的项目拆分为模块。我有 4 个模块:Web、服务、存储库、域。除了JSP之外，一切正常，spring找不到这些页面。但是，当我没有将项目拆分为模块时，它就可以工作了。我没有更改配置。

这是我的网络模块结构

enter image description here

Runner 位于 web 模块中，这里是:

@SpringBootApplication(scanBasePackages = "kz.epam.javalab.daimoncool")
public class WebApplication {

    public static void main(String[] args) {
        SpringApplication.run(WebApplication.class, args);
    }

}

这是我的应用程序属性:

spring.mvc.throw-exception-if-no-handler-found=true
spring.resources.add-mappings=false

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

spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
spring.http.encoding.force=true

spring.datasource.driver-class-name=oracle.jdbc.driver.OracleDriver
spring.datasource.url=jdbc:oracle:thin:@localhost:1521:orcl
spring.datasource.username=
spring.datasource.password=
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.Oracle10gDialect
spring.jpa.properties.hibernate.physical_naming_strategy=com.vladmihalcea.hibernate.type.util.CamelCaseToSnakeCaseNamingStrategy

如果你能帮助我，我会很高兴)我再说一遍，当没有模块时它可以工作，不改变配置，只是添加模块它不起作用。

Intellij IDEA 还向我显示，即使我显式添加 View 解析器 bean，index.jsp 也没有 View 解析器

最佳答案

我发现了问题。我需要更改 intellij IDEA 中的工作目录。 Spring Boot 运行程序采用根路径，然后查找 jsp(在我的例子中它是父项目)。但我的运行器位于 Web 模块中，因此我需要 Spring Boot 运行器将根路径更改为 Web 模块(通过更改工作目录)，而不是父级。
