This article mainly explains "the framework of Java and its advantages and disadvantages". Interested friends may wish to have a look at it. The method introduced in this paper is simple, fast and practical. Let the editor take you to learn the framework of Java and the introduction of its advantages and disadvantages.

1 、 SpringMVC

As a Chinese saying goes, "Ginger is still old and spicy", so although SpringMVC has been released for more than a decade, it is still old and strong, with an absolute advantage in the leading position. After embracing the complete MVC framework, Spring continues to evolve and has now become a comprehensive Java framework for Internet applications, providing software engineers with powerful toolkits for Web application development and application configuration for security projects. As the favorite of programmers, Spring's well-developed ecosystem offers a number of additional options: RESTAPI or SOAPWeb services, security (authentication and authorization, encryption), and so on. In addition, many large companies choose to use SpringMVC, so if you encounter problems in the process, there will be a lot of technology cows can answer for you.

Advantages and disadvantages

It is not without reason that Spring has reached the top with an absolute advantage, and it has become the best-known Java framework mainly because:

1. Use POJO to simplify the injection of test data.

two。 Enhanced modularity makes the code more readable.

3. Decoupling between different modules.

4. Flexible application of dependency injection (DI).

Although SpringMVC has a lot of documentation to refer to, its learning curve is still too steep for novice Java developers, and developers may not know how to start when they come across parts with few reference documents. In addition, although there is a lot of information on SpringMVC, there are differences in different versions. Overall, SpringMVC is one of the favorite frameworks for engineers.

2 、 Struts2

In order to explain in more detail the Java framework widely used by modern software engineers, here Qianfeng Wuhan Java training teacher introduces the subsequent version of ApacheStruts1, Struts2. Struts2 is used to build contemporary JavaEEWeb applications. The Apache Software Foundation provides developers with a wide range of tools for creating enterprise-level Web-oriented applications that optimize the development process throughout, even late maintenance, to optimize the development process and post-maintenance to the end. If you are worried about a high-load system, such as a broadcast portal, then Struts will be your best choice.

Because Struts2 implements the Action class (a plain POJO object), it takes less effort to test and write code. With the framework API, coupling becomes easier, helping to adjust the interceptor.

Advantages and disadvantages

The biggest feature of Struts2 is that there is no need to rewrite or implement the Action class, and it is no longer a problem for IT engineers to create duplicate setup code for multiple operations, because the interceptor handles it.

The biggest disadvantage of Struts is that it is not flexible enough.

3 、 Hibernate

Although Hibemate is not on the RebelLabs list, it is still a Java framework worth mentioning. This mapping Java framework solves the problem of mismatch between objects and relationships and uses continuous database access operations to replace high-level object processing functions. Applications in each enterprise are different, so Hibernate comes with a powerful suite of features to help back-end developers fine-tune the data access layer. This is an advanced ORM framework that allows you to perform database operations on Java objects (entities). Using Hibernate caching to persist data from the Java environment to the database is a persistence concept.

Advantages and disadvantages

Hibernate can help you communicate with any database by making minor changes to the original code, bridging the gap between objects and relationships. In addition to this advantage, it also has:

1. Whether Oracle, Db2 or MySQL,Hibernate exist independently of DB.

two。 The caching mechanism optimizes similar queries.

3. Support for Number1 or lazy loading.

Although Hibernate has many advantages, it does not allow multiple inserts, does not support some queries of JDBC, and is not suitable for small-scale projects with fewer tables.

4 、 JSF

As part of JavaEE, Oracle supports JavaServerFaces. Although this is not the best framework for rapid development of Java, it is easy to get started because Oracle provides a lot of documentation. If you don't leave the JavaEE environment, JSF has no external dependencies, but it is powerful, and it has a rich set of libraries and tools (including a toolset that is easy to create a user interface) that can be supported no matter how complex your application looks.

Advantages and disadvantages

As mentioned above, JSF is a part of JavaEE. As a result, developers can take advantage of the IDE software suite and a high level of support from industry-leading suppliers.

But there are two sides to everything. Web Server faces is so large that it may be difficult for people with no JavaServer development experience or unskilled technology to master it.

5 、 Vaadin

Vaadin is one of the popular frameworks that modern developers must choose when creating business applications and rendering end-of-page pages using GWT. Vaadin uses a well-known component-based approach to quickly adapt to changes in browsers, thereby reducing the burden on developers. Vaadin eliminates the burden on developers by communicating changes to browsers. In the age of rich UI components, a variety of widgets and controls, programmers can build a cool application anytime, anywhere.

Advantages and disadvantages

In the layout construction of Java or HTML, Vaadin provides available methods for MVC or MVP to bind data. Support for drag-and-drop and other prominent features simplify the creation of a single-page UI for Java applications.

Because Vaadin needs to post back each event to the server, it may cause the UI of the mobile application to be slow.

6 、 GoogleWebToolkit

GWT is a free Java framework that allows users to create and optimize complex Web-based applications. GWT's software development kit provides the core JavaAPI and widgets that can be built and compiled into JavaScript applications.

Advantages and disadvantages

With GoogleWebToolkit, you have access to a single code base (browser and server-side programming in Java), simplifying the development and debugging process. Simple integration with other technologies allows programmers to embed GWT widgets in Web pages. Widget functionality can also be customized with the help of GWT.

However, GWT is not suitable for HTML and later dynamic content layout, so it can not meet the needs of web designers.

At this point, I believe you have a deeper understanding of the "introduction of the framework and advantages and disadvantages of Java". You might as well do it in practice. Here is the website, more related content can enter the relevant channels to inquire, follow us, continue to learn!
