}spring boot Use hutool to integrate email Send email file
Import dependencies
Hutool is an optional dependency on all third parties, so you need to introduce third-party dependencies yourself when using MailUtil.
Old version
<dependency>
<groupId>com.sun.mail</groupId>
<artifactId>javax.mail</artifactId>
<version>1.6.2</version>
</dependency>New version
<dependency> <groupId>com.sun.mail</groupId> <artifactId>jakarta.mail</artifactId> <version>1.6.7</version> </dependency>
You can also directly daoru spring boot email dependency
<!--spring mail start-->
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-mail</artifactId>
</dependency>Configuration file
In the classpath (in the standard Maven project Create a new mail.setting file in the config directory of src/main/resources). The minimum configuration content is as follows. Under this configuration, both the SMTP server and user name will be identified through the from parameter. : form user is the file sending address user of Alibaba Cloud mailbox is the complete address of the mailbox, that is, xxx@aliyun .com
# 邮件服务器的SMTP地址，可选，默认为smtp.<发件人邮箱后缀> host = smtp.yeah.net # 邮件服务器的SMTP端口，可选，默认25 port = 25 # 发件人（必须正确，否则发送失败） from = hutool@yeah.net # 用户名，默认为发件人邮箱前缀 user = hutool # 密码（注意，某些邮箱需要为SMTP服务单独设置授权码，详情查看相关帮助） pass = q1w2e3
Test
@GetMapping("testEmail")
public String send() {
MailUtil.send("123@qq.com", "测试", "邮件来自Hutool测试", false);
return "ok";
} You can also send files, just refer to the hutool document

How Springboot integrates Jasypt to implement configuration file encryption
Jun 01, 2023 am 08:55 AM
Introduction to Jasypt Jasypt is a java library that allows a developer to add basic encryption functionality to his/her project with minimal effort and does not require a deep understanding of how encryption works. High security for one-way and two-way encryption. , standards-based encryption technology. Encrypt passwords, text, numbers, binaries... Suitable for integration into Spring-based applications, open API, for use with any JCE provider... Add the following dependency: com.github.ulisesbocchiojasypt-spring-boot-starter2. 1.1Jasypt benefits protect our system security. Even if the code is leaked, the data source can be guaranteed.
How to use Redis to implement distributed locks in SpringBoot
Jun 03, 2023 am 08:16 AM
1. Redis implements distributed lock principle and why distributed locks are needed. Before talking about distributed locks, it is necessary to explain why distributed locks are needed. The opposite of distributed locks is stand-alone locks. When we write multi-threaded programs, we avoid data problems caused by operating a shared variable at the same time. We usually use a lock to mutually exclude the shared variables to ensure the correctness of the shared variables. Its scope of use is in the same process. If there are multiple processes that need to operate a shared resource at the same time, how can they be mutually exclusive? Today's business applications are usually microservice architecture, which also means that one application will deploy multiple processes. If multiple processes need to modify the same row of records in MySQL, in order to avoid dirty data caused by out-of-order operations, distribution needs to be introduced at this time. The style is locked. Want to achieve points
How SpringBoot integrates Redisson to implement delay queue

Usage scenario 1. The order was placed successfully but the payment was not made within 30 minutes. The payment timed out and the order was automatically canceled. 2. The order was signed and no evaluation was conducted for 7 days after signing. If the order times out and is not evaluated, the system defaults to a positive rating. 3. The order is placed successfully. If the merchant does not receive the order for 5 minutes, the order is cancelled. 4. The delivery times out, and push SMS reminder... For scenarios with long delays and low real-time performance, we can Use task scheduling to perform regular polling processing. For example: xxl-job Today we will pick
How to solve the problem that springboot cannot access the file after reading it into a jar package
Jun 03, 2023 pm 04:38 PM
Springboot reads the file, but cannot access the latest development after packaging it into a jar package. There is a situation where springboot cannot read the file after packaging it into a jar package. The reason is that after packaging, the virtual path of the file is invalid and can only be accessed through the stream. Read. The file is under resources publicvoidtest(){Listnames=newArrayList();InputStreamReaderread=null;try{ClassPathResourceresource=newClassPathResource("name.txt");Input
Comparison and difference analysis between SpringBoot and SpringMVC
Dec 29, 2023 am 11:02 AM
SpringBoot and SpringMVC are both commonly used frameworks in Java development, but there are some obvious differences between them. This article will explore the features and uses of these two frameworks and compare their differences. First, let's learn about SpringBoot. SpringBoot was developed by the Pivotal team to simplify the creation and deployment of applications based on the Spring framework. It provides a fast, lightweight way to build stand-alone, executable

How to implement Springboot+Mybatis-plus without using SQL statements to add multiple tables
Jun 02, 2023 am 11:07 AM
When Springboot+Mybatis-plus does not use SQL statements to perform multi-table adding operations, the problems I encountered are decomposed by simulating thinking in the test environment: Create a BrandDTO object with parameters to simulate passing parameters to the background. We all know that it is extremely difficult to perform multi-table operations in Mybatis-plus. If you do not use tools such as Mybatis-plus-join, you can only configure the corresponding Mapper.xml file and configure The smelly and long ResultMap, and then write the corresponding sql statement. Although this method seems cumbersome, it is highly flexible and allows us to
How to get the value in application.yml in springboot
Jun 03, 2023 pm 06:43 PM
In projects, some configuration information is often needed. This information may have different configurations in the test environment and the production environment, and may need to be modified later based on actual business conditions. We cannot hard-code these configurations in the code. It is best to write them in the configuration file. For example, you can write this information in the application.yml file. So, how to get or use this address in the code? There are 2 methods. Method 1: We can get the value corresponding to the key in the configuration file (application.yml) through the ${key} annotated with @Value. This method is suitable for situations where there are relatively few microservices. Method 2: In actual projects, When business is complicated, logic
