引入jar包

spring boot打包的插件

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

                </executions>

            </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;

/**

@Configuration

        filterRegistrationBean.setFilter(new CORSFilter());

        filterRegistrationBean.addUrlPatterns("/*");

        return filterRegistrationBean;

    }

    //字符集utf-8

    @Bean

    public FilterRegistrationBean characterRegistrationBean() {

        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();

        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();

    }

    //--------------------------------Listener

        return sessionListener;

    }

//    --------------------------------------Servlet

    @Bean

    public ServletRegistrationBean dispatcher() {
