打断点的操作:
源码:
private List<View> getCandidateViews(String viewName, Locale locale, List<MediaType> requestedMediaTypes) throws Exception {
List<View> candidateViews = new ArrayList();
if (this.viewResolvers != null) {
Assert.state(this.contentNegotiationManager != null, "No ContentNegotiationManager set");
Iterator var5 = this.viewResolvers.iterator();
while(var5.hasNext()) {
ViewResolver viewResolver = (ViewResolver)var5.next();
View view = viewResolver.resolveViewName(viewName, locale);
if (view != null) {
candidateViews.add(view);
}
Iterator var8 = requestedMediaTypes.iterator();
while(var8.hasNext()) {
MediaType requestedMediaType = (MediaType)var8.next();
List<String> extensions = this.contentNegotiationManager.resolveFileExtensions(requestedMediaType);
Iterator var11 = extensions.iterator();
while(var11.hasNext()) {
String extension = (String)var11.next();
String viewNameWithExtension = viewName + '.' + extension;
view = viewResolver.resolveViewName(viewNameWithExtension, locale);
if (view != null) {
candidateViews.add(view);
}
}
}
}
}
if (!CollectionUtils.isEmpty(this.defaultViews)) {
candidateViews.addAll(this.defaultViews);
}
return candidateViews;
}
MyMvcConfig.java 自定义视图解析器
package com.kuang.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.View;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
import java.util.Locale;
//扩展 springmvc
//如果你想要的自定义一些定制化的功能,只要写这个组件,然后将它交给springboot, springboot就会帮我们自动装配
@Configuration //将这个类变成配置类
public class MyMvcConfig implements WebMvcConfigurer {
//public interface ViewResolver 实现了视图解析器接口的类,我们就可以把它看做视图解析器
@Bean
public ViewResolver myViewResolver(){
return new MyViewResolver();
}
//自定义了一个视图解析器
public static class MyViewResolver implements ViewResolver{
@Override
public View resolveViewName(String s, Locale locale) throws Exception {
return null;
}
}
}
源码:
@Bean
public FormattingConversionService mvcConversionService() {
Format format = this.mvcProperties.getFormat();
WebConversionService conversionService = new WebConversionService((new DateTimeFormatters()).dateFormat(format.getDate()).timeFormat(format.getTime()).dateTimeFormat(format.getDateTime()));
this.addFormatters(conversionService);
return conversionService;
}
方式一:
这么多的自动配置,原理都是一样的,通过这个WebMVC的自动配置原理分析,我们要学会一种学习方式,通过源码探究,得出结论。
SpringBoot的底层,大量用到了这些设计细节的思想,所以要多读源码。
SpringBoot在自动配置很多组件的时候,先看容器中有没有用户自己配置的(如果用户自己配置@bean),如果有就用用户配置的,如果没有就用自动配置的;如果有些组件可以存在多个,比如我们的视图解析器,就将用户配置的和自己默认的组合起来。
源码:获取所有的WebMvcConfigurer:
@Autowired(
required = false
)
public void setConfigurers(List<WebMvcConfigurer> configurers) {
if (!CollectionUtils.isEmpty(configurers)) {
this.configurers.addWebMvcConfigurers(configurers);
}
}
源码:
@ConditionalOnClass({
Servlet.class, DispatcherServlet.class, WebMvcConfigurer.class})
@ConditionalOnMissingBean({
WebMvcConfigurationSupport.class})
@AutoConfigureOrder(-2147483638)
@AutoConfigureAfter({
DispatcherServletAutoConfiguration.class, TaskExecutionAutoConfiguration.class, ValidationAutoConfiguration.class})
public class WebMvcAutoConfiguration {
public static final String DEFAULT_PREFIX = "";
public static final String DEFAULT_SUFFIX = "";
private static final String[] SERVLET_LOCATIONS = new String[]{
"/"};
public WebMvcAutoConfiguration() {
}
MyMvcConfig.java 视图跳转
package com.kuang.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
//如果我们要扩展springmvc,官方建议我们这样去做
@Configuration
@EnableWebMvc //这个就是导入了一个类: DelegatingWebMvcConfiguration:从容器中获取所有的webmvcconfig
public class MyMvcConfig implements WebMvcConfigurer {
//视图跳转
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/kuang").setViewName("test");
}
}
在springboot中,有非常多的xxxx Configuration(配置类)帮助我们进行扩展配置,只要看见了这个东西,我们就要注意了。
访问index页面的方式一:
IndexController
package com.kuang.controller;
import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
//首页控制
@Controller
public class IndexController {
@RequestMapping({
"/","/index.html"})
public String index(){
return "index";
}
}
方式二:
package com.kuang.config;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurer;
@Configuration
public class MyMvcConfig implements WebMvcConfigurer {
@Override//添加视图控制
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("index");// 到了/走到index
registry.addViewController("/index.html").setViewName("index");
}
}
访问结果:
不改成thymeleaf形式静态资源加载不了,所有的图标都看不了
1.首页配置:注意点,所有页面的静态资源都需要使用thymeleaf接管。由于是url 所以使用 @{}
application.properties 这个是更改了查看路径:
# 关闭模板引擎缓存
spring.thymeleaf.cache=false
server.servlet.context-path=/kuang
通过查看页面的源代码可以看到里面已经自动配置了/kuang
2国际化
首先确定设置为utf-8,避免乱码:
可视化编写:
点击Text和Resource Bundle可以切换界面
LocaleResolver
3.登录 + 拦截器
4.员工列表展示
1.提取公共页面
th:fragment="sidebar"
<div th:replace="~{commons/commons::sidebar(active='main.html')}">div>
如果要传递参数,可以直接使用()传参,接收判断即可。
列表循环展示。

//如果请求的链接携带了国际化的参数
if (!StringUtils.isEmpty((language))){

//国家 地区 static public final Locale ENGLISH = createConstant("en", "");
