spring老项目转springboot项目 笔记

引入jar包

先不删除老的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-->
        <resources>

            </resource>
            <resource>

                <includes>
                    <include>**/*</include>

                </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;

/**
 * 对应web.xml
 *
 * @author songaw
 * @date 2018/7/17 9:10
 */
@Configuration
public class WebConfig {
    //----------------------Filter
    //跨域过滤器
    @Bean
    public FilterRegistrationBean corsRegistrationBean() {
        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," +

        reg.setServlet(dispatcherServlet);
        reg.addUrlMappings("*.do");
        reg.setLoadOnStartup(30);

    }

  
    //阿里druid界面设置

        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;
import com.fasterxml.jackson.databind.ObjectMapper;

import org.springframework.web.servlet.resource.VersionResourceResolver;
import org.springframework.web.servlet.view.InternalResourceViewResolver;
import org.springframework.web.servlet.view.JstlView;

import java.util.ArrayList;
import java.util.List;
import java.util.concurrent.TimeUnit;

@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {

    /**
     * 添加拦截器
     * @param registry
     */
    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(new LocaleChangeInterceptor());
    //    registry.addInterceptor(webInterceptor());
    }

    /**
     *
     * @param converters
     */
    @Override
    public void configureMessageConverters(List<HttpMessageConverter<?>> converters) {
        //用来忽略json对象传入，反序列化时候属性名称不正确导致序列化失败的bug
        MappingJackson2HttpMessageConverter jacksonMessageConverter = new MappingJackson2HttpMessageConverter();
        List<MediaType> supportedMediaTypes =new ArrayList<>();
//        避免IE执行AJAX时，返回JSON出现下载文件
        supportedMediaTypes.add(MediaType.TEXT_HTML);
        jacksonMessageConverter.setSupportedMediaTypes(supportedMediaTypes);
        ObjectMapper mapper = jacksonMessageConverter.getObjectMapper();
        mapper.configure(DeserializationFeature.FAIL_ON_UNKNOWN_PROPERTIES, false);
        converters.add(jacksonMessageConverter);
    }

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        registry.viewResolver(this.getViewResolver());
        //MappingJsonView jsonView = new MappingJsonView();
    //    registry.enableContentNegotiation(jsonView);
    }

    @Bean
    public ViewResolver getViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setViewClass(JstlView.class);
        resolver.setPrefix("/WEB-INF/jsp/");
        resolver.setSuffix(".jsp");
        resolver.setOrder(1);
        return resolver;
    }
    @Override
    public void addViewControllers(ViewControllerRegistry registry){
        registry.addViewController("/").setViewName("forward:/login.html");
    }
    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        VersionResourceResolver versionResourceResolver = new VersionResourceResolver();
        versionResourceResolver.addVersionStrategy(new ContentVersionStrategy(), "/**");
        registry.addResourceHandler("/resources/**")
                .addResourceLocations("/resources/")
                .resourceChain(true)
                .addResolver(versionResourceResolver);
    }

    @Bean
    public EmbeddedServletContainerFactory servletContainer() {
        TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
        factory.setSessionTimeout(14400, TimeUnit.SECONDS);
        ErrorPage ep1 = new ErrorPage(HttpStatus.NOT_FOUND, "/index.html");
        return factory;
    }

}

3. spring.xml转配置文件
