Migrating the Spring Boot application to Java 9: CompatibilityWith the advent of Java 9, there is a lot of discussion about how to migrate applications to use modular systems. Unfortunately, most of the articles focus on the simple Hello World program. Or worse, for Spring applications, the sample application uses traditional practices-such as using XML as an example.The purpose of this article is to correc

Historical Theory of Spring (Data desensitization) and Historical Theory of spring Desensitization At present, the architecture of many companies has been migrated from Struts2 to SpringMVC. Have you ever wondered why SpringMVC is used instead of Servlet + JSP to build a Java web project? In this case, let's start with the source. The source of Struts2 is actually Servlet. Servlet is used to receive request

Just yesterday Spring Boot2.0.0.RELEASEOfficially released, this morning in the release of Spring Boot2.0 in a small episode, the spring Boot2.0 sync to the Maven warehouse when there was an error, and then spring boot officials quickly released on GitHub The V2.0.0.release version was withdrawn. In the afternoon to fi

Problem: 1. See this a bit Meng, just started to think that the JDK is not a problem. So: Yes, no problem. Continue to think, since the error is to find what this Maven bin directory, cmd Open, naturally look at this: Since it is java_home

Let's use spring boot to develop a simple "Hello World" web app, built using MAVEN. Before you begin, check your version of Java and Maven to see if it is a supported version of Spring boot1.3:$ Java-versionjava Version "1.8.0_45" Java (tm) SE Runtime Environment (build 1.8.0_45-b14) Java HotSpot (tm) 64-bit Server V M (build 25.45-b02, Mixed mode)$ mvn-vapache m

Spring: Use Spring AOP to separate log input and method. spring AOP Log output is a common function. The traditional method is to write the output statement inside the method body. When calling this method, use the input statement output information to record the execution of the method! 1. First write a common class: Package com. importnew; public class Common {

Preparatory workFirst, build a simple Web project that will be used to add security controls later, and if you are building a web app using spring boot, you can read the Spring Boot Development web App article first.Web tier Implementation Request mapping@Controller Public class Hellocontroller { @RequestMapping ("/") public String Index () { return "Index"; } @RequestMapping ("/hell

Spring el--spring Expression language: Supports the use of expressions in XML and annotations, similar to the El Expression language of JSPs. Spring development often involves invoking a variety of resources, including common files, URLs, configuration files, system environment variables, and so on, and we might use spring's expression language to implement reso

also need to introduce the Jasper package dependencies that are used to compile the JSP. After adding JSP support configuration, the following a method and B method is to jump to the/web-inf/jsp/regiester.jsp page.

processing, the purpose is to encapsulate data. 8.Servlet is how the request is handled usually when we send a request like Http://localhost:8080/TomcatTest/login, How does the container find the Loginservlet class to handle it? In fact, Tomcat has a mapper class that is designed to hold the child container information in the container container in Tomcat, Before the Org.apache.catalina.connector.Request class goes into the container container, Mapper will be based on this request hostname, C

Next we will create a web project. For simplicity, We will directly use the template in Virgo to create a new project. The control layer uses spring MVC 3.Create a WEB Project Open STS and create a project. Select sprinng template project.

[Spring] uses Spring's AbstractRoutingDataSource to implement multi-data source switching. spring dynamically switches data sources. Recently, because the project needs to synchronize data between two projects, specifically, Project 1 data is synchronized to project 2 through the message queue, because this update operation also involves updating data in multiple databases, you need to switch between multip

If you use JUnit's liberary, you can complete the test of the program. In spring development, Spring provides the relevant test modules, which makes it easy to load the configuration files and test them. How to use: The first step: Introduction of the test package, found in the download of the Spring package Lib: Add jar to project and build path Step Two: Wr

Using MAVEN to create a Java Web project (Spring MVC) uses the following tools:1. Maven 3.22, IntelliJ idea 133. JDK 1.74. Spring 4.1.1 Released5, TOMCAT76.

The above describes the process of developing an application based on spring boot, and its documentation is not yet complete, but there are a number of examples on GitHub, including integrated access to the database with

1. The content of the article is summarized:The spring framework is MAVEN-enabled, because the jar packages packaged by all the modules of the spring framework and other jar packages that spring relies on are stored in a central Maven repository, and if your project is managed using MAVEN, Then you can use MAVEN in your project to introduce the
