多个RestTemplate对象示例

@Configuration
public class MyConfiguration {

    @LoadBalanced
 5     @Bean
    RestTemplate loadBalanced() {
        return new RestTemplate();
    }

    @Primary
11     @Bean
    RestTemplate restTemplate() {
        return new RestTemplate();
    }
}

public class MyClass {
    @Autowired
    private RestTemplate restTemplate;

    @Autowired
    @LoadBalanced
    private RestTemplate loadBalanced;

    public String doOtherStuff() {
        return loadBalanced.getForObject("http://stores/stores", String.class);
    }

    public String doStuff() {
        return restTemplate.getForObject("http://example.com", String.class);
    }
}

 如果发现报这个错误

java.lang.IllegalArgumentException: Can not set org.springframework.web.client.RestTemplate field com.my.app.Foo.restTemplate to com.sun.proxy.$Proxy89

试试注入RestOperations或者加上spring.aop.proxyTargetClass=true
