引入jar包

先不删除老的jar包

spring boot打包的插件

  <build>
        <finalName>MIS</finalName>
        <!-- maven 打包不全（xml，properties文件没打进包）解决方案-->

            </plugin>
        </plugins>
    </build>

创建springboot主类

package com.guige;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.web.support.SpringBootServletInitializer;
import org.springframework.context.annotation.ComponentScan;

@SpringBootApplication
@ComponentScan({"com.guige.oim.v2.*"})public class Application extends SpringBootServletInitializer {

    @Override    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {        return application.sources(Application.class);
    }    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }
}

创建application.properties文件

#默认前缀
server.contextPath=/#数据源
spring.datasource.name=adminDataSource
spring.datasource.driverClassName = oracle.jdbc.OracleDriver
spring.datasource.url = spring.datasource.username = spring.datasource.password =

1.先把web.xml去掉

创建core包

web.xml里的servlet转成bean形式

filter也一样

创建WebConfig配置类

package com.guige.core.conf;

import com.alibaba.druid.support.http.StatViewServlet;
import com.alibaba.druid.support.http.WebStatFilter;
import com.guige.core.ext.i18n.filter.LocaleFilter;
import com.guige.mis.filter.JspFilter;
import com.guige.mis.listener.ContextListener;
import com.guige.mis.listener.OnlineUserListener;
import com.guige.oim.filter.CORSFilter;
import com.guige.oim.servlet.*;
import org.springframework.boot.web.servlet.FilterRegistrationBean;
import org.springframework.boot.web.servlet.ServletListenerRegistrationBean;
import org.springframework.boot.web.servlet.ServletRegistrationBean;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.CharacterEncodingFilter;
import org.springframework.web.servlet.DispatcherServlet;/**

        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
        filterRegistrationBean.setFilter(new CORSFilter());
        filterRegistrationBean.addUrlPatterns("/*");        return filterRegistrationBean;
    }    //字符集utf-8    @Bean    public FilterRegistrationBean characterRegistrationBean() {
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");
        characterEncodingFilter.setForceEncoding(true);
        filterRegistrationBean.setFilter(characterEncodingFilter);
        filterRegistrationBean.addUrlPatterns("/*");        //filterRegistrationBean.addInitParameter("encoding", "UTF-8");       // filterRegistrationBean.addInitParameter("ForceEncoding", "true");
        return filterRegistrationBean;
    }    //对jsp进行权限日志过滤    @Bean    public FilterRegistrationBean jspFilterRegistrationBean() {
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
        JspFilter jspFilter = new JspFilter();
        filterRegistrationBean.setFilter(jspFilter);
        filterRegistrationBean.addUrlPatterns("*.do");        return filterRegistrationBean;
    }    /**
     * 如果session中没有设置locale串或者locale串不合法，默认采用request的locale，
     * @return     */
    @Bean    public FilterRegistrationBean localeRegistrationBean() {
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
        filterRegistrationBean.setFilter(new LocaleFilter());
        filterRegistrationBean.addUrlPatterns("*.do");        return filterRegistrationBean;
    }    //阿里druid界面设置    @Bean    public FilterRegistrationBean webStatFilterRegistrationBean() {
        FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
        filterRegistrationBean.setFilter(new WebStatFilter());
        filterRegistrationBean.addUrlPatterns("/*");
        filterRegistrationBean.addInitParameter("exclusions", "*.js,*.gif,*.jpg,*.png,*.css,*.ico,/druid/*");        return filterRegistrationBean;
    }    //--------------------------------Listener
    @Bean    public ServletListenerRegistrationBean<OnlineUserListener> onlineUserListenerRegistrationBean(){
        ServletListenerRegistrationBean<OnlineUserListener>
                sessionListener = new ServletListenerRegistrationBean<OnlineUserListener>(new OnlineUserListener());        return sessionListener;

    }
    @Bean    public ServletListenerRegistrationBean<ContextListener> contextListenerRegistrationBean(){
        ServletListenerRegistrationBean<ContextListener>
                sessionListener = new ServletListenerRegistrationBean<ContextListener>(new ContextListener());        return sessionListener;

    }//    --------------------------------------Servlet
    @Bean    public ServletRegistrationBean dispatcher() {

        ServletRegistrationBean reg = new ServletRegistrationBean();
        DispatcherServlet dispatcherServlet = new DispatcherServlet();
        dispatcherServlet.setContextConfigLocation("classpath:config/core/spring-mvc.xml," +                " classpath:config/core/dao/dao_authority.xml," +                " classpath:config/core/dao/dao_manager.xml," +                " classpath:config/core/dao/dao_oim.xml," +                " classpath:config/core/dao/dao_oim_v2.xml," +                " classpath:config/core/dao/dao_orgacus.xml," +                " classpath:config/core/service/service_authority.xml," +                " classpath:config/core/service/service_manager.xml," +                " classpath:config/core/service/service_oim.xml," +                " classpath:config/core/service/service_oim_v2.xml," +                " classpath:config/core/service/service_orgacus.xml," +                " classpath:config/client/i18n.xml," +                " classpath:config/client/http.xml," +                " classpath:config/client/action/action_main.xml," +                " classpath:config/client/action/action_authority.xml," +                " classpath:config/client/action/action_manager.xml," +                " classpath:config/client/action/action_oim.xml," +                " classpath:config/client/action/action_oim_v2.xml," +                " classpath:config/client/action/action_orgacus.xml");
        reg.setServlet(dispatcherServlet);
        reg.addUrlMappings("*.do");
        reg.setLoadOnStartup(30);        return reg;
    }  
    //阿里druid界面设置    @Bean    public ServletRegistrationBean statViewServlet() {

        ServletRegistrationBean reg = new ServletRegistrationBean();
        reg.setServlet(new StatViewServlet());
        reg.addUrlMappings("/druid/*");
        reg.addInitParameter("loginUsername", "111");
        reg.addInitParameter("loginPassword", "111");        return reg;
    }

}

2.spring mvc文件

里面的bean 转成声明试bean

package com.guige.core.conf;

import com.alibaba.druid.support.http.WebStatFilter;
import com.fasterxml.jackson.databind.DeserializationFeature;

@Configurationpublic class WebMvcConfig extends WebMvcConfigurerAdapter {    /**

        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);

Vue.observable()进行状态管理
随着组件的细化，就会遇到多组件状态共享的情况， Vuex当然可以解决这类问题，不过就像 Vuex官方文档所说的，如果应用不够大，为避免代码繁琐冗余，最好不要使用它，今天我们介绍的是 vue.js 2.6 新增加的 Observable API ，通过使用这个 api 我们可以应对一些简单的跨组件数据状态共享的情况。

MongoDB日志文件查看
默认情况下，MongoDB在此路径/var/log/mongodb/mongodb.log创建日志文件，如果找不到该日志文件，请检查MongoDB配置文件。

app抓包无数据
我们经常在wifi设置中设置代理到我们的pc http代理软件上，多数情况下，此时我们开启的app流量都可以在代理软件上看到，比如charles ， fiddler等等。但是细心的人会发现某些大厂的app 某些请求在这些 http代理软件上就是抓不到，给人的感觉就是流量没从代理软件走一样。

app抓不到包，解决很简单
1.手机安装virtualXpost 并激活xpost 框架，如有问题自行百度。 2.安装justTrustMe，然后再virtualXpost中添加此模块 3.安装手机抓包神器packet capture 4.在virtualXpost中运行app，并打开packet capture抓包就行
