Spring Boot的web开发
在spring-boot-autoconfigure-1.5.2.RELEASE.jar中，
Web开发的自动配置类：org.springframework.boot.autoconfigure.web.WebMvcAutoConfiguration
自动配置的ViewResolver
视图的配置mvcProperties对象中：
org.springframework.boot.autoconfigure.web.WebMvcProperties.View
- 在
application.prrperties中自定义配置prefix
"NoHandlerFoundException" should be thrown if no Handler was found to process a request.
spring.mvc.view.prefix= # Spring MVC view prefix.
spring.mvc.view.suffix= # Spring MVC view suffix.
自动配置静态资源
-
进入规则为
/
如果进入SpringMVC的规则为/时，Spring Boot的默认静态资源的路径为：
spring.resources.static-locations=classpath:/META-INF/resources/,classpath:/resources/,classpath:/static/,classpath:/public/
静态资源路径
浏览器访问路径 -
进入规则为
*.xxx或者 不指定静态文件路径时
将静态资源放置到webapp下的static目录中即可通过地址访问：
自定义消息转化器
自定义消息转化器，只需要在@Configuration的类中添加消息转化器的@bean加入到Spring容器，就会被Spring Boot自动加入到容器中。
@Bean
public StringHttpMessageConverter stringHttpMessageConverter(){
StringHttpMessageConverter converter = new StringHttpMessageConverter(Charset.forName("UTF-8"));
return converter;
}
默认配置：
自定义SpringMVC的配置
有些时候我们需要自已配置SpringMVC而不是采用默认，比如说增加一个拦截器，这个时候就得通过继承WebMvcConfigurerAdapter然后重写父类中的方法进行扩展。
package cn.huachao.springboot.controller;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
@Configuration
public class MySpringMVCConfig extends WebMvcConfigurerAdapter{
@Override
public void addInterceptors(InterceptorRegistry registry) {
HandlerInterceptor handlerInterceptor = new HandlerInterceptor() {
@Override
public boolean preHandle(HttpServletRequest request, HttpServletResponse response, Object handler) throws Exception {
System.out.println("自定义拦截器............");
return true;
}
@Override
public void postHandle(HttpServletRequest request, HttpServletResponse response, Object handler,
ModelAndView modelAndView) throws Exception {
}
@Override
public void afterCompletion(HttpServletRequest request, HttpServletResponse response, Object handler,
Exception ex)throws Exception {
}
};
registry.addInterceptor(handlerInterceptor);
}
// 自定义消息转化器的第二种方法
@Override
public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
StringHttpMessageConverter converter = new StringHttpMessageConverter(Charset.forName("UTF-8"));
converters.add(converter);
}
}
