To learn spring cloud, to install the Spring boot Spring-tool-suite plug-in, I installed in the first time, due to improper operation, two geniuses completely installed, really is dead, feel stupid to die! Below you have stepped on the pit and some tips to share with you. Installation method: (I used eclipse, so I took

mappings are implemented with a-p parameter. For example, we mapped the 6379 port of the Redis container to the 6378 port on this machine:Docker run-d-P 6378:6379--name Port-redis RedisDelete ContainerDocker RM Container-idRemove all containersDocker RM $ (Docker ps-a-Q)View current Container LogDocker logs Container-name/container-idSuch as:Docker logs Port-redisLanding containerA running container is actually a fully functional Linux operating syst

There are many kinds of API document automatic generation tools, such as: Swagger Spring REST Docs RAML Apidocjs Springrestdoc This article evaluates and compares these popular API document generation tools: https://opencredo.com/ rest-api-tooling-review/ Swagger is one of the more recommended. Characteristics of Swagger:1. Configuration in spring boot is very

Quick StartThe main objective of this chapter is to build the Spring Boot Foundation project and implement a simple HTTP request processing, which gives a preliminary understanding of spring boot and experiences its simple structure and rapid development.System Requirements: Java 7 and above

whole business, it is some log or other auxiliary code. And many businesses need the same functionality, such as the need to log, it is necessary to copy the functions of these logging, even if it is packaged into a framework, but also need to call. Using complex design patterns here is not worth the candle.So we have to face the plane.3. Building AOPOriginally, Spring came with a set of AOP implementations, and we used this implementation directly,

It is believed that many people choose spring boot primarily because it takes into account the power of spring and the ease with which it can be developed quickly. In the spring boot use process, the most intuitive feeling is not the original integration of the

same set of programs is usually applied and installed into several different environments, such as: development, testing, production, etc. Each environment's database address, server port and so on configuration will be different, if you are packaging for different environments to frequently modify the configuration file, it will be a very cumbersome and prone to error.For a multi-environment configuration, the basic idea of a variety of project buil

Spring Boot configuration mybatis and transaction managementFirst, spring boot and MyBatis configuration1. First, the full dependencies required for spring boot configuration mybatis are as follows:Parent>Groupid>org.springframewo

1.JPAJPA (Java Persistence API) is the Java Persistence specification proposed by Sun. It provides Java developers with an object/association mapping tool to manage relational data in Java applications. The main purpose of his presence is to simplify existing persistent development efforts and integrate ORM technology, and to end the current Hibernate,toplink,jdo and other ORM frameworks for each battalion. It is worth noting that JPA is developed on the basis of fully absorbing the existing HIB

Static resource accessWhen we develop Web applications, we need to reference a large number of JS, CSS, pictures and other static resources.Default configurationSpring boot defaults to provide a static resource directory location to be placed under Classpath, and the directory name must conform to the following rules:/static/public/resources/meta-inf/resourcesExample: We can create a static in the src/main/resources/directory, where a picture file is

For example, if we were to introduce support for Web MVC in spring boot, we would usually introduce this module spring-boot-starter-web, which, if unpacked, would find nothing in it and only defined some pom dependencies.After study, starter is mainly used to simplify the us

Spring Boot attribute configuration and custom attribute Configuration In the process of using spring boot, we can find that the project can complete the corresponding functions with only a few configurations, thanks to the modular configuration in spring

This part is generally divided into controller layer, service layer, persistence layer. In addition, there are some data encapsulation class

Preparatory workFirst, build a simple Web project that you can use to add security controls later, or use the Chapter3-1-2 as a foundation project. If you are building a web app using spring boot, you can first read the article "Spring Boot Development web App".Web tier Implementation Request mapping@Controllerpublic c

JdkSerializationRedisSerializer by default, which means that both the key and value are serialized through Java. StringRedisTemplate uses StringRedisSerializer by default. For example, if RedisTemplate is used, we want to serialize the value of the Product type to JSON, and the key is of the String type. The setKeySerializer () and setValueSerializer () Methods of the RedisTemplate must be as follows: @ Bean public RedisTemplate redisTemplate (RedisC

We complete our example by creating a fully self-contained executable jar file that can be run in production env. An executable jar (sometimes called a "fat jars") is an archive file that contains the classes you compile and all the jar dependencies your code needs to run.This example continues on the basis of Spring Boot
