java - 我的 Java Spring 项目构建成功，但在日志中给我错误
问题描述
我有java spring 项目。当我构建项目时，项目构建成功但在日志中给我这个错误：- java.io.IOException：java.lang.reflect.InvocationTargetException。Т他的项目工作正常。但是我想在构建项目时删除日志中的这个错误
告诉我问题出在 Application.java 中的这一行 - SpringApplication.run(Application.class, args);
这是我的 Application.java
package com.zetcode;
import org.springframework.boot.SpringApplication;

import org.springframework.boot.web.servlet.support.SpringBootServletInitializer;
import org.springframework.context.ApplicationContext;

@SpringBootApplication
public class Application extends SpringBootServletInitializer {

SpringApplication.run(Application.class, args);
}
@Resource

viewResolver.setViewNames(new String[] {"thyme/*"});
viewResolver.setExcludedViewNames(new String[] {"jsp/*"});
viewResolver.setTemplateEngine(springTemplateEngine);
viewResolver.setCharacterEncoding("UTF-8");
return viewResolver;
}
@Bean
public InternalResourceViewResolver jspViewResolver(){
final InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
viewResolver.setViewClass(JstlView.class);
viewResolver.setPrefix("/templates/");
viewResolver.setSuffix(".jsp");
viewResolver.setViewNames("jsp/*");
return viewResolver;
}
@Bean
public SpringResourceTemplateResolver thymeleafTemplateResolver(){
final SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
templateResolver.setApplicationContext(applicationContext);
templateResolver.setPrefix("/templates/");
templateResolver.setSuffix(".html");
templateResolver.setTemplateMode(TemplateMode.HTML);
templateResolver.setCacheable(false);
templateResolver.setOrder(0);
return templateResolver;
}
@Bean
public SpringResourceTemplateResolver jspTemplateResolver(){
final SpringResourceTemplateResolver templateResolver = new SpringResourceTemplateResolver();
templateResolver.setApplicationContext(applicationContext);
templateResolver.setPrefix("/templates/");
templateResolver.setSuffix(".jsp");
templateResolver.setTemplateMode(TemplateMode.HTML);
templateResolver.setCacheable(false);
templateResolver.setOrder(1);
templateResolver.setCharacterEncoding("UTF-8");
return templateResolver;
}
}
这是日志

解决方案
您需要禁用嵌入式 tomcat 清单扫描。
@Bean
public TomcatServletWebServerFactory tomcatFactory() {
return new TomcatServletWebServerFactory() {
@Override
protected void postProcessContext(Context context) {
((StandardJarScanner) context.getJarScanner()).setScanManifest(false);
}};
}
