Thymeleaf

# 关闭模板缓存
spring.thymeleaf.cache=false
# Thymeleaf页面位置
spring.thymeleaf.prefix=classpath:/templates/
spring.thymeleaf.suffix=.html

MVC自定义

添加@Configuration注解

package com.example.SpringBoot.config;

import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;

/**
 * @author Zero
 * mvc配置
 */
@Configuration
public class MyMvcConfig implements WebMvcConfigurer {
    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("index");
        registry.addViewController("/index").setViewName("index");
        registry.addRedirectViewController("/", "index");
        registry.addRedirectViewController("/index", "index");
    }
}

国际化

package com.example.SpringBoot.config;

import org.springframework.web.servlet.LocaleResolver;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import java.util.Locale;

/**
 * @author Zero
 * 国际化
 */
public class MyLocaleResolver implements LocaleResolver {
    @Override
    public Locale resolveLocale(HttpServletRequest request) {
        return null;
    }

    @Override
    public void setLocale(HttpServletRequest request, HttpServletResponse response, Locale locale) {

    }
}
