如何在Spring boot中设置UTF-8字符编码?

I use spring-boot in my project, and I run this jar file which is built by spring-boot as a service on Centos. When I run this service:

我在我的项目中使用spring-boot，并运行这个jar文件，它是通过spring-boot作为Centos的服务构建的。当我运行这个服务:

service myApp start

服务myApp开始

I always get the below error messages:

我总是收到下面的错误信息:

If I run this jar file directly, then this application runs properly.

如果我直接运行这个jar文件，那么这个应用程序就会正常运行。

java -jar target/myApp-1.0.jar

目标/ myApp-1.0.jar java jar

在Centos的场所设置:

LC_COLLATE="en_US.UTF-8"

LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=en_US.UTF-8

I check all files setting as possible as I do, however I still have no idea how to solve this problem. I would appreciate if you can give me any suggestion.

我尽可能的检查所有文件的设置，但是我还是不知道如何解决这个问题。如果你能给我任何建议，我将不胜感激。

4 个解决方案

#1

SOLUTION

Add to config file (for application /var/app/app.jar it will be /var/app/app.conf) below line:

添加到配置文件中(用于应用程序/var/ app/app/app。jar它将是/var/app/app.conf)下面的行:

export LANG='en_US.UTF-8'

---

CAUSE

The problem is in linux systemd (service). I tested it with script /etc/init.d/test:

问题在于linux系统(服务)。我用script /etc/init.d/test测试了它:

#/bin/bash
locale

result of command $ /etc/init.d/test:

命令的结果$ /etc/init.d/test:

LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"
LC_ALL=

and result of command $ service test:

和命令$服务测试结果:

LANG=
LC_CTYPE="POSIX"
LC_NUMERIC="POSIX"
LC_TIME="POSIX"
LC_COLLATE="POSIX"
LC_MONETARY="POSIX"
LC_MESSAGES="POSIX"
LC_PAPER="POSIX"
LC_NAME="POSIX"
LC_ADDRESS="POSIX"
LC_TELEPHONE="POSIX"
LC_MEASUREMENT="POSIX"
LC_IDENTIFICATION="POSIX"
LC_ALL=

In spring boot jar file is build-in systemd script and before running spring boot is executed among others:

在spring boot jar文件中内置systemd脚本，在运行spring boot之前执行以下操作:

# Source any config file
configfile="$(basename "${jarfile%.*}.conf")"

# Initialize CONF_FOLDER location defaulting to jarfolder
[[ -z "$CONF_FOLDER" ]] && CONF_FOLDER="${jarfolder}"

# shellcheck source=/dev/null
[[ -r "${CONF_FOLDER}/${configfile}" ]] && source "${CONF_FOLDER}/${configfile}"

#2

Finally I found a way so that I can launch Spring-boot project properly.

最后我找到了一种方法，使我能够正确地启动Spring-boot项目。

The solution is use sudo /etc/init.d/myApp start instead of service myApp start

解决方法是使用sudo /etc/ init。d/myApp start而不是myservice app start

#3

The first line tells you that you should set system property 'file.encoding'. I think that's the problem. Please see: Setting the default Java character encoding?

第一行告诉您应该设置系统属性“file.encoding”。我认为这就是问题所在。请参见:设置默认的Java字符编码?

Based on my answer here: https://*.com/a/48952844/986160 you need to run:

根据我的回答:https://*.com/a/48952844/986160你需要运行:

mvn spring-boot:run -Drun.jvmArguments="-Dfile.encoding=UTF-8"
