springboot1.5.12升级为springboot2.3.2流程_Java

1 先修改pom.xml配置将1.5.12改成2.3.2

 <!--<parent>-->
        <!--<groupId>org.springframework.boot</groupId>-->
        <!--<artifactId>spring-boot-starter-parent</artifactId>-->
        <!--<version>1.5.12.RELEASE</version>-->
        <!--<relativePath/>-->
    <!--</parent>-->
    <parent>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-parent</artifactId>
        <version>2.3.2.RELEASE</version>
        <relativePath/>
    </parent>

启动过程发现我项目有个alibaba的库有问题原来是1.1.0升级为1.1.10就好了

 <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.10</version>
        </dependency>

2 修改yml配置文件

2.1 spring.datasource增加一个druid对象

spring:
  datasource:
    druid:
      url:  jdbc:mysql://xxxxxxxx:xxxx/xx?useSSL=false&useUnicode=true&characterEncoding=utf8&allowMultiQueries=true&useAffectedRows=true
      username: xxxx
      password: xxxx
      driver-class-name: com.mysql.jdbc.Driver

2.2 redis增加一个jedis对象

spring:
  redis:
    database: 2
    host: xxxxx
    port: xxx
    password: xxx
    jedis:
      pool:
        max-active: 1000
        max-wait: -1
        max-idle: 10
        min-idle: 2
    timeout: 10000

2.3 修改mutipart对象属性原来是

maxFileSize: 10Mb
maxRequestSize: 100Mb

注意MB和Mb

 http:
  servlet:
    multipart:
      max-request-size: 10MB
      max-file-size: 100MB

3 静态资源拦截

顺利启动后，访问swagger 报错 ResourceHttpRequestHandler cannot be cast to org.springframework.web.method.HandlerMethod。就是静态资源被拦截了。

严重: Servlet.service() for servlet [dispatcherServlet] in context with path [] threw exception [Request processing failed; nested exception is java.lang.ClassCastException: org.springframework.web.servlet.resource.ResourceHttpRequestHandler cannot be cast to org.springframework.web.method.HandlerMethod] with root cause

在拦截器哪里增加过滤规则这里我贴出来整个类，相关的规则就是最后面几行配置白名单那里。

package com.todo.controller.permissions;


import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.config.annotation.InterceptorRegistry;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;

import java.util.Arrays;

/**
 * @Author XLN
 * @Description 拦截器
 **/
@Configuration
public class WebMvcConfig extends WebMvcConfigurerAdapter {

	@Override
	public void addResourceHandlers(ResourceHandlerRegistry registry) {
		registry.addResourceHandler("/**")
		.addResourceLocations("classpath:/META-INF/resources/")
				.addResourceLocations("file:C:/videos_dev/");
	}

	@Bean
	public AuthorityInterceptor miniInterceptor() {
		return new AuthorityInterceptor();
	}

	/**
	 * @Author XLN
	 * @Description 配置拦截器
	 * @Date 2019-05-16
	 **/
	@Override
	public void addInterceptors(InterceptorRegistry registry) {
		/**
		 * 配置白名单
		 */
		registry.addInterceptor(miniInterceptor())
				.addPathPatterns("/**")
				.excludePathPatterns(Arrays.asList("/views/**", "/res/**"))
				.excludePathPatterns("/swagger-ui.html")
				.excludePathPatterns("/webjars/**")
				.excludePathPatterns("/api/login")
						.excludePathPatterns("/api/sendMsg");
		super.addInterceptors(registry);
	}

}

至此项目顺利启动。
