網上找了很多關於font-awesome在ie8中不顯示的解決辦法，但是都沒有效果，最後嘗試把本地能夠在ie8中正常顯示字型的demo移植到spring-boot中發現在ie8中就是顯示不了，所以得出結論font-awesome在ie8中字型不顯示應該和框架的配置有關係，網上找到了解決方法如下

<build>
        <resources>
            <resource>
                <directory>${project.basedir}/src/main/resources</directory>
                <filtering>true</filtering>
                <excludes>
                    <exclude>**/*.woff</exclude>
                    <exclude>**/*.ttf</exclude>
                    <exclude>**/*.eot</exclude>
                    <exclude>**/*.svg</exclude>
                </excludes>

            </resource>

            <resource>
                <directory>${project.basedir}/src/main/resources</directory>
                <filtering>false</filtering>
                <includes>
                    <include>**/*.woff</include>
                    <include>**/*.ttf</include>
                    <include>**/*.eot</include>
                    <include>**/*.svg</include>
                </includes>
            </resource>

        </resources>

	    <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <version>1.4.0.RELEASE</version>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <version>3.0.1</version>
                <configuration>
                    <nonFilteredFileExtensions>
                        <nonFilteredFileExtension>woff</nonFilteredFileExtension>
                        <nonFilteredFileExtension>eot</nonFilteredFileExtension>
                        <nonFilteredFileExtension>ttf</nonFilteredFileExtension>
                        <nonFilteredFileExtension>svg</nonFilteredFileExtension>
                    </nonFilteredFileExtensions>
                </configuration>
            </plugin>

        </plugins>
	</build>  
 

然後還發現一個問題，我的font-awesome.css配置如下，同事電腦中沒有src: url('../fonts/fontawesome-webfont.eot');這一行程式碼也會顯示不出來

@font-face {
    font-family: 'FontAwesome';
    src: url('../fonts/fontawesome-webfont.eot');
    src: url('../fonts/fontawesome-webfont.eot?#iefix&v=4.2.0') format('embedded-opentype');
    src: url('../fonts/fontawesome-webfont.eot?v=4.2.0'), url('../fonts/fontawesome-webfont.woff?v=4.2.0') format('woff'), url('../fonts/fontawesome-webfont.ttf?v=4.2.0') format('truetype'), url('../fonts/fontawesome-webfont.svg?v=4.2.0#fontawesomeregular') format('svg');
    font-weight: normal;
    font-style: normal
}
