多个RestTemplate对象示例

Posted 2020-10-17 那啥快看

 1 @Configuration
 2 public class MyConfiguration {
 3 
 4     @LoadBalanced
 5     @Bean
 6     RestTemplate loadBalanced() {
 7         return new RestTemplate();
 8     }
 9 
10     @Primary
11     @Bean
12     RestTemplate restTemplate() {
13         return new RestTemplate();
14     }
15 }
16 
17 public class MyClass {
18     @Autowired
19     private RestTemplate restTemplate;
20 
21     @Autowired
22     @LoadBalanced
23     private RestTemplate loadBalanced;
24 
25     public String doOtherStuff() {
26         return loadBalanced.getForObject("http://stores/stores", String.class);
27     }
28 
29     public String doStuff() {
30         return restTemplate.getForObject("http://example.com", String.class);
31     }
32 }

 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
