Error resolving template [sys/prod/prod/list], template might not exist or might not be accessible by any of the configured Template Resolvers
新的商城模板调试接口,一个商品列表的接口调用,返回报错
org.thymeleaf.exceptions.TemplateInputException: Error resolving template [sys/prod/prod/list], template might not exist or might not be accessible by any of the configured Template Resolvers at org.thymeleaf.engine.TemplateManager.resolveTemplate(TemplateManager.java:869) at org.thymeleaf.engine.TemplateManager.parseAndProcess(TemplateManager.java:607) at org.thymeleaf.TemplateEngine.process(TemplateEngine.java:1098) at org.thymeleaf.TemplateEngine.process(TemplateEngine.java:1072) at org.thymeleaf.spring5.view.ThymeleafView.renderFragment(ThymeleafView.java:362) at org.thymeleaf.spring5.view.ThymeleafView.render(ThymeleafView.java:189)
问题原因:
在controller上加注解@Controller 和@RestController都可以在前端调通接口,但是二者的区别在于,当用前者的时候在方法上必须添加注解@ResponseBody,
如果不添加@ResponseBody,就会报上面错误,因为当使用@Controller 注解时,spring默认方法返回的是view对象(页面)。
而加上@ResponseBody,则方法返回的就是具体对象了。
@RestController的作用就相当于@Controller+@ResponseBody的结合体
修改为@RestController 后正常
