如何配置RestTemplate以与不同的URL和响应实体一起使用？

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web</artifactId>
    </dependency>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-web-services</artifactId>
    </dependency>
</dependencies>

RestTemplate restTemplate = new RestTemplate();

RestTemplate restTemplate = new RestTemplateBuilder().build();

String url = "http://example.com/api/resource";
ResponseEntity<String> response = restTemplate.getForEntity(url, String.class);
String responseBody = response.getBody();

String url = "http://example.com/api/resource/{id}";
String id = "123";
ResponseEntity<String> response = restTemplate.getForEntity(url, String.class, id);
String responseBody = response.getBody();
