The main content of this article is "how to solve the problem of garbled codes in Springboot-application.properties". Interested friends may wish to have a look. The method introduced in this paper is simple, fast and practical. Let's let the editor take you to learn "how to solve the problem of garbled codes in Springboot-application.properties".

Springboot-application.properties Chinese garbled code

Springboot-application.properties coding problem set application.properties to utf-8 read configuration Chinese result printing analysis

Set application.properties to utf-8

UTF-8, so that viewing configuration files in windows and linux servers can display Chinese normally. Otherwise, Chinese may not be displayed properly.

The configuration in application.properties is as follows:

Demo.to-who= Zhang San reads the configured Chinese @ RestControllerpublic class TestController {@ Value ("${demo.to-who}") private String toWho; @ RequestMapping ("/ test2") public Object test2 () throws UnsupportedEncodingException {System.out.println (toWho); System.out.println (new String (toWho.getBytes ("iso8859-1") System.out.println (new String (toWho.getBytes ("iso8859-1"), "utf-8"); return null;}} result printing

You need to change the data encoding from iso8859-1 to utf-8 before it can be used properly.

One thousand per thousand.

Analysis.

In the source code

Private static class CharacterReader implements Closeable {/ / other codes omit CharacterReader (Resource resource) throws IOException {this.reader = new LineNumberReader (new InputStreamReader (resource.getInputStream (), StandardCharsets.ISO_8859_1));} / / other codes are omitted}

In other words, no matter which encoding format the application.properties file is set to, it will eventually be loaded in the encoding format of ISO-8859-1.

Yml/yaml is loaded with UTF-8 by default.

Springboot configuration file application.properties supports Chinese version notes

This article is not entirely based on springboot-2.4.5, each version needs to rewrite the logic of the class is different, the code in this article can only be imitated, can not be copied

Why is the Chinese PropertySourceLoader interface not supported?

First take a look at the interface org.springframework.boot.env.PropertySourceLoader that reads the configuration file.

='0' & & digit > loadProperties (Resource resource) throws IOException {String filename = resource.getFilename (); List result = new ArrayList (); if (filename! = null & & filename.endsWith (XML_FILE_EXTENSION)) {result.add ((Map) PropertiesLoaderUtils.loadProperties (resource)) } else {List documents = new MyOriginTrackedPropertiesLoader (resource). Load (); documents.forEach ((document)-> result.add (document.asMap ());} return result;}} 3. Create a spring.factories file

Create the / META-INF/spring.factories file under the resources resource directory

The contents of the file are

Org.springframework.boot.env.PropertySourceLoader=\ com.xxx.config.MyPropertiesPropertySourceLoader test

Create an application.properties file

Abc= Chinese test

Create the service class and inject the abc variable using @ Value

@ Value ("${abc}") private String abc

Break points in the load method of the com.xxx.config.MyPropertiesPropertySourceLoader class, the org.springframework.boot.env.PropertiesPropertySourceLoader class, and the org.springframework.boot.env.YamlPropertySourceLoader class

Running the project as debug, you can see that only the com.xxx.config.MyPropertiesPropertySourceLoader class and the org.springframework.boot.env.YamlPropertySourceLoader class are loaded

Send a request to view the value of the abc variable: Chinese test, no garbled code

At this point, I believe you have a deeper understanding of "how to solve the problem of garbled codes in Springboot-application.properties". 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!
