我正在使用Spring Boot 2.0.0.RELEASE，Thymeleaf，Spring Security，JDK 10，Apache Tomcat 9.0.6。我有控制器
package com.donhuvy.controller;

import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RequestParam;
import org.springframework.web.servlet.ModelAndView;
import java.util.Optional;
@Controller
@RequestMapping("/ccy")
public class CcyController {
private static final int INITIAL_PAGE = 0;
private static final int INITIAL_PAGE_SIZE = 10;
@Autowired
CcyRepository ccyRepository;
@RequestMapping(value = "/all", method = RequestMethod.GET)
public ModelAndView getAllPaginatingCcy(
@RequestParam("pageSize") Optional<Integer> pageSize,
@RequestParam("page") Optional<Integer> page) {
int evalPageSize = pageSize.orElse(INITIAL_PAGE_SIZE);
int evalPage = (page.orElse(0) < 1) ? INITIAL_PAGE : page.get() - 1;
Page<Ccy> currencies = ccyRepository.findAll(PageRequest.of(evalPage, evalPageSize));
ModelAndView modelAndView = new ModelAndView("cash/ccy");
modelAndView.addObject("currencies", currencies);
return modelAndView;
}
@GetMapping("/vy")
public String foo(@RequestParam("pageSize") Optional<Integer> pageSize,
@RequestParam("page") Optional<Integer> page, Model model){

Page<Ccy> currencies = ccyRepository.findAll(PageRequest.of(evalPage, evalPageSize));
model.addAttribute("currencies", currencies);
return "cash/ccy";
}
}
在application.properties我有
spring.mvc.view.prefix=templates/
spring.mvc.view.suffix=.html
我有配置类

As a result, the response may have the wrong status code. If your application is running on WebSphere Application Server you may be able to resolve this problem by setting com.ibm.ws.webcontainer.invokeFlushAfterService to false

如何解决？
答案 0 :(得分：3)
您可以通过在Spring配置中进行配置来禁用ErrorPageFilter来删除错误日志：
@Bean
public ErrorPageFilter errorPageFilter() {
return new ErrorPageFilter();
}
@Bean
public FilterRegistrationBean<Filter> disableSpringBootErrorFilter(ErrorPageFilter filter) {
FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
filterRegistrationBean.setFilter(filter);
filterRegistrationBean.setEnabled(false);
return filterRegistrationBean;
}
在Spring Boot中，通过配置第二个@Bean就足够了。

对我来说，这是由我的 jsp 中的 <s:include> 指向一个无法找到的文件引起的。
我的 Java 控制台和日志显示 org.springframework.boot.web.servlet.support.ErrorPageFilter : Cannot forward to error page for request [/my-app/my-app-sub] as the response has already been committed.，而网络浏览器显示 404。
当我更正我在 <s:include> 中提供的文件位置时，错误消失了。
答案 2 :(得分：0)
我错过了Thymeleaf依赖。我必须将此行添加到build.gradle
compile ('org.springframework.boot:spring-boot-starter-thymeleaf:2.0.0.RELEASE')
