spring expression read file content

Question

How to use spring expression to read file content and put it into a string?

I would like to do the following.

For example,

@Value(\"classpath         


        

Answer 1

There is a similar question answered here which use Java configuration.

@Configuration
public class Spring {

    @Value("classpath:choice-test.html")
    private Resource sampleHtml;

    @Bean
    public String sampleHtmlData() {
        try(InputStream is = sampleHtml.getInputStream()) {
            return IOUtils.toString(is);
        }
    }
}

Answer 2

Finally got the answer myself...

@Value("#{T(org.apache.commons.io.FileUtils).readFileToString(" +
    "T(org.springframework.util.ResourceUtils).getFile('classpath:myquery.sql')" +
    ")}")
String sql;

sql is now default filled by the exact content of myquery.sql under classpath
