Sorting out the answers to Daniel: 1. Get started looking at documents (blogs, books, etc.), in-depth understanding of the meaning of the configuration file (Spring, Struts, Hibernate); 2. Encounter problems, self-solve, if resolved, why this solution? (Always ask a question why) 3. Specifically to hibernate, the first thing to learn is the database, JDBC, design patterns, these are the foundation. My personal understanding: Always ask w

This class is the start listener of spring, which must be in the web. xml configuration to modify the listener, the default load WEB-INF/applicationcontext1.xml configuration file, of course, you can customize the configuration file name through the configuration, such as WEB-INF/* context. XML, WEB-INF/spring *. XML "or" WEB-INF/ #42; #42;/* context. XML is acc

Of course, if you use Spring 4.x, you have provided the custom UrlPathHelper configuration: The code is as follows:Copy

The cutting techniques in the next spring are described in the previous section, and now we are going to use annotations to cut slices.First of all, it must be the same as before, requiring an automatic proxy annotation class AnnotationawareaspectjautoproxycreatorCode in the configuration file:In the configuration file, we are not difficult to find, the most basic is a proxy object, automatic proxy class, slice (can be the class you write, this annota

class, you can pass the GetMessage () method to get the Internationalized file content.So how easy is it to get the ApplicationContext implementation class? This time requires another interface, that is, "Applicationcontextaware", any class implementation of this interface, will be injected into the applicationcontext. Public classSpringutilImplementsApplicationcontextaware {Private StaticApplicationContext ApplicationContext; Public StaticApplicationContext Getapplicationcontext () {returnApp

in spring:Keyword Explanation:Hibernate is a third-party class library that uses objects to access the database, and of course it is well-known that we can establish a connection between the table and the entity class simply by configuring the XML for the relationship between the entity class and the table in the database.DAO is our own definition of what we want to do with the database in the project. Templete is a tool for adding and removing chang

returned by the JSON format of the response, but IE will mistakenly think of these JSON response is a file transfer, and then directly pop up the download box to ask if you need to download.The workaround is to change the response header from Content-type:application/json to Content-type:text/plain or text/htmlThe following Java backend code:@RequestMapping (value = "/uploadurl", method = Requestmethod.post, produces = {"Text/plain"}) public {

Today we build a simple MAVEN project based on the Springboot SSM (Spring + SPRINGMVC + mybatis) that uses a database of MySQL. Well, the nonsense is not much to say. Start to get up.

We created the structure using idea's own creation springboot, and of course it was possible to create ordinary Web pro
