读取resource下文件

ArrayList<PatrolOper> patrolOpers = new ArrayList<>();

 String jsonData = null;
 File jsonFile = null;
 try {
     jsonFile = ResourceUtils.getFile("classpath:jsonRequest.json");
 } catch (FileNotFoundException e) {
     e.printStackTrace();
 }
 try {
     jsonData = FileUtils.readFileToString(jsonFile,"UTF-8");
 } catch (IOException e) {
     e.printStackTrace();
 }

Gson gson = new Gson();
 PatrolTaskOperRequest bean = gson.fromJson(jsonData, PatrolTaskOperRequest.class);

主要在于，加载了好几次，都发现class下没json文件，后来发现，maven 对resource有过滤。

<!--配置Maven 对resource文件 过滤 -->
<resources>
    <resource>
        <directory>src/main/resources</directory>
        <includes>
            <include>**/*.properties</include>
            <include>**/*.xml</include>
            <include>**/*.json</include>
        </includes>
        <filtering>true</filtering>
    </resource>
    <resource>
        <directory>src/main/java</directory>
        <includes>
            <include>**/*.properties</include>
            <include>**/*.xml</include>
        </includes>
        <filtering>true</filtering>
    </resource>
</resources>
