前言
我写的第一个项目终于迎来了尾声，将spirngmvc转成成spirngboot可能是这个项目的最后一次重构了。在期间遇见了一些问题，随着问题的攻破也收获了很多宝贵经验，用此文章分享一下我的项目重构过程。
1、更改依赖
mvc依赖文件

注：由于依赖过多影响篇幅，删去一些
springboot只是对依赖进行了版本控制，但并不会将依赖全部导入，需要哪些依赖还需手动添加。
2、更改配置文件
将原来的spirng.xml、springmvc.xml等配置文件删除，添加application.yml文件：
根据spring、springmvc中的配置对application配置进行修改。
以下是部分application配置文件：
spring:
mvc:
pathmatch:
matching-strategy: ant_path_matcher
hiddenmethod:
filter:
enabled: true
static-path-pattern: /static/**
thymeleaf:
prefix: classpath:/templates/ # thymeleaf解析器前缀
suffix: .html # thymeleaf解析器后缀
servlet:
multipart:
max-file-size: 10MB # 设置文件上传的最大大小
max-request-size: 100MB # 设置请求的最大大小
mybatis:
configuration:
log-impl: org.apache.ibatis.logging.stdout.StdOutImpl
default-statement-timeout: 3000
map-underscore-to-camel-case: true # 开启驼峰转下划线
server:
port: 8080 # 端口
servlet:
context-path: /Diet # 项目名
encoding:
charset: UTF-8
reactive:
session:
timeout: 30m # session最大保留时间
3、更改资源目录，设置WebMvcConfig
将webapp目录下的资源放进resources目录下
删除web.xml，并配置webmvcconfig文件来替代web.xml
@Configuration //继承WebMvcConfigurer接口
public class MySpringMvcConfigurer implements WebMvcConfigurer {
//视图解析器
@Override
public void addViewControllers(ViewControllerRegistry registry) {
registry.addViewController("/").setViewName("redirect:/home");
}
//配置ResourceHandler访问静态资源
//笔者此处是为了解决swagger-ui被莫名拦截的问题，无此问题的小伙伴可以跳过
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("swagger-ui.html")
.addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("doc.html")
.addResourceLocations("classpath:/META-INF/resources/");
registry.addResourceHandler("/webjars/**")
.addResourceLocations("classpath:/META-INF/resources/webjars/");
}
//添加登录拦截器、管理员拦截器
@Override
public void addInterceptors(InterceptorRegistry registry) {
registry.addInterceptor(new UserLoginInterceptor())
.addPathPatterns("/**")
.excludePathPatterns("/static/**","/home","/login","/","/users/login"
,"/register","/users/register","/users/initUserInfo","/mainPicture/getMainPictures"
,"/RecipeControl/ToRecipe","/notes/toNoteById","/getMenuToMeduMainPage","/note"
,"/users/personalSpace","/toMenu","/notes/getNote","/admins/**","/adminlogin"
,"/webjars/**","/v2/**","/swagger-ui.html/**","/users/sendCode","/mainPicture/**"
,"/swagger-resources/**","/comment/getComment");
registry.addInterceptor(new AdminInterceptor())
.addPathPatterns("/admins/**","/mainPicture/**")
.excludePathPatterns("/mainPicture/getMainPictures","/admins/adminLogin");
}
}
4、添加启动类
启动类位置应比项目文件高一级
@org.springframework.boot.autoconfigure.SpringBootApplication//启动类注解
@ComponentScan("net.wlgzs")//
@EnableSwagger2 //swagger注解，在生产环境可以删除
public class SpringBootApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootApplication.class,args);
}
}
目录结构：
spirngboot：
springmvc：
springmvc转spirngboot并不是很难，因为spirngboot本就是为了简化开发而生。
