前後端分離 SpringBoot 專案，如何將 vue 打進 jar 包中

背景介紹

客戶需要將專案前後端作為一個整體打包成jar，不使用nginx方式轉發。使用框架是若依前後端分離，後端springboot，前端vue，目的就是把vue打入jar。

前端修改

1. ruoyi-ui/src/router/index.js檔案 ，將 mode: ‘history’ 改成 mode: ‘hash’

export default new Router({
  mode: 'hash', 
  scrollBehavior: () => ({ y: 0 }),
  routes: constantRoutes
})

2. 修改ruoyi-ui/.env.production檔案 將’/prod-api’ 改成’/’

# 生產環境
VUE_APP_BASE_API = '/'

3. 去bin裡build前端專案

後端修改

1. 引入依賴spring-boot-starter-thymeleaf

        <dependency>
		<groupId>org.springframework.boot</groupId>
		<artifactId>spring-boot-starter-thymeleaf</artifactId>
        </dependency>

2. 修改yml檔案配置（dev和local可以都改），增加thymeleaf配置

# Spring配置
spring:
  thymeleaf:
    prefix: classpath:/dist/
    mode: HTML
    encoding: utf-8
    cache: false

3. 修改ResourcesConfig檔案內容,新增以下部分addViewControllers

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/index").setViewName("index.html");
        registry.addViewController("/").setViewName("index.html");
        registry.setOrder(Ordered.HIGHEST_PRECEDENCE);
    }

4. 修改ResourcesConfig檔案內容,替換addResourceHandlers內容如下：

@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
    /** 本地檔案上傳路徑 */
    registry.addResourceHandler(Constants.RESOURCE_PREFIX + "/**").addResourceLocations("file:" + RuoYiConfig.getProfile() + "/");
    /** 頁面靜態化 */
    registry.addResourceHandler("/static/**").addResourceLocations("classpath:/dist/static/");
    /** swagger配置 */
    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/");
}

5. 根據情況配置訪問許可權修改ruoyi-framework專案中的SecurityConfig.java類，配置靜態資源訪問許可權

如果全放行可以不用管，可以把程式碼中的.anyRequest().authenticated()那行註釋掉

package com.ruoyi.framework.config;

@EnableGlobalMethodSecurity(prePostEnabled = true, securedEnabled = true)
public class SecurityConfig extends WebSecurityConfigurerAdapter{
    @Override
    protected void configure(HttpSecurity httpSecurity) throws Exception    {
        httpSecurity
                // CSRF禁用，因為不使用session
                .csrf().disable()
                // 認證失敗處理類
                .exceptionHandling().authenticationEntryPoint(unauthorizedHandler).and()
                // 基於token，所以不需要session
                .sessionManagement().sessionCreationPolicy(SessionCreationPolicy.STATELESS).and()
                // 過濾請求
                .authorizeRequests()
                // 對於登入login 驗證碼captchaImage 允許匿名訪問
                .antMatchers("/login", "/captchaImage").anonymous()
                .antMatchers(
                        HttpMethod.GET,
                        "/*.html",
                        "/**/*.html",
                        "/**/*.css",
                        "/**/*.js",
                        "/static/**",
                        "/",
                        "/index"
                ).permitAll()
                .antMatchers("/profile/**").anonymous()
                .antMatchers("/common/download**").anonymous()
                .antMatchers("/common/download/resource**").anonymous()
                .antMatchers("/swagger-ui.html").anonymous()
                .antMatchers("/doc.html").anonymous()
                .antMatchers("/swagger-resources/**").anonymous()
                .antMatchers("/webjars/**").anonymous()
                .antMatchers("/*/api-docs").anonymous()
                .antMatchers("/druid/**").anonymous()
                // 除上面外的所有請求全部需要鑑權認證
                .anyRequest().authenticated()
                .and()
                .headers().frameOptions().disable();
        httpSecurity.logout().logoutUrl("/logout").logoutSuccessHandler(logoutSuccessHandler);
        // 新增JWT filter
        httpSecurity.addFilterBefore(authenticationTokenFilter, UsernamePasswordAuthenticationFilter.class);
        // 新增CORS filter
        httpSecurity.addFilterBefore(corsFilter, JwtAuthenticationTokenFilter.class);
        httpSecurity.addFilterBefore(corsFilter, LogoutFilter.class);
    }
}

6. 把前端build完成的dist目錄放到ruoyi-admin專案的resources目錄下

7. 最後去後端打包編譯 package.bat，java -jar執行專案，瀏覽器訪問http://localhost:8080
