React+SpringBoot打包War部署Tomcat遇白标错误求助
React + SpringBoot 打包成War后部署Tomcat出现白标错误
我需要把React前端和SpringBoot后端打包成单个War文件,部署到Tomcat(内置/外置均可)。
项目文件夹结构:
我使用的Gradle构建任务如下:
node { download=false workDir = file("${project.projectDir}/frontend/nodejs") npmWorkDir = file("${project.projectDir}/frontend/npm") nodeModulesDir = file("${project.projectDir}/frontend") } task appNpmInstall(type: NpmTask){ description = " read packge.json and install all jars" workingDir = file("${project.projectDir}/frontend") args =["install"] } task appNpmBuild(type: NpmTask){ description = "Builds applciation for your frontend " workingDir = file("${project.projectDir}/frontend") args =["run", "build"] } task copyToFrontend(type: Copy){ from "$projectDir/frontend/build" into "$buildDir/resources/main/static" } appNpmBuild.dependsOn appNpmInstall copyToFrontend.dependsOn appNpmBuild compileJava.dependsOn copyToFrontend
打包后已验证War包内WEB-INF->classes下存在static文件夹:
我尝试了两种部署方式:
- 内置Tomcat:
java -jar build/libs/automation.war - 外置Tomcat部署
但访问localhost:8080或localhost:8080/index.html时,均出现白标错误页面:
日志中报错信息:
2024-11-11 15:55:00.072 WARN 11844 --- [nio-8080-exec-4] .w.s.m.s.DefaultHandlerExceptionResolver : Resolved [org.springframework.web.method.annotation.MethodArgumentTypeMismatchException: Failed to convert value of type 'java.lang.String' to required type 'java.lang.Long'; nested exception is java.lang.NumberFormatException: For input string: "index.html"]
有没有遇到过这类问题的?求可行的解决方案,我可以提供更多细节。
