quarkus读取.txt文件内容解析成json对象

可以使用Java的标准库和第三方库来实现这个需求,以下是一种可能的实现方式:
1. 使用Java的标准库读取.txt文件内容,可以使用BufferedReader类和FileReader类来实现。具体代码如下:
```
File file = new File("file.txt");
BufferedReader reader = new BufferedReader(new FileReader(file));
String line;
StringBuilder content = new StringBuilder();
while ((line = reader.readLine()) != null) {
content.append(line);
}
reader.close();
```
2. 解析文本内容并转换成JSON对象,可以使用第三方库如Jackson,代码如下:
```
ObjectMapper objectMapper = new ObjectMapper();
JsonNode jsonNode = objectMapper.readTree(content.toString());
```
其中,content为上一步中读取到的文件内容字符串。
完整代码示例:
```
import java.io.BufferedReader;
import java.io.File;
import java.io.FileReader;
import java.io.IOException;
import com.fasterxml.jackson.databind.JsonNode;
import com.fasterxml.jackson.databind.ObjectMapper;
public class TxtToJson {
public static void main(String[] args) throws IOException {
File file = new File("file.txt");
BufferedReader reader = new BufferedReader(new FileReader(file));
String line;
StringBuilder content = new StringBuilder();
while ((line = reader.readLine()) != null) {
content.append(line);
}
reader.close();
ObjectMapper objectMapper = new ObjectMapper();
JsonNode jsonNode = objectMapper.readTree(content.toString());
System.out.println(jsonNode);
}
}
```
注意,需要在pom.xml文件中添加Jackson库的依赖:
```
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
<artifactId>jackson-core</artifactId>
<version>2.12.4</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.core</groupId>
