重点分析Object bean=resolveBeforeInstantiation(beanName,mbdToUse);//和第一次的场景一样: 如果返回值不为空,那么说明要对原因对象进行了修改,那么直接返回修改后的对象即可//这里可以进行动态代理!!!//如果这里直接返回,也就形成了所谓的短路现象if(bean!=null){returnbean;}}catch(Throwable ex){thrownewBean...
return (descriptor.getField() != null ? converter.convertIfNecessary(value, type, descriptor.getField()) : converter.convertIfNecessary(value, type, descriptor.getMethodParameter())); } } // 集合类型 bean 解析,比如:数组、Map、Stream 和 Collection Object multipleBeans = resolveMultipleBeans(descr...
AutowiredAnnotationBeanPostProcessor.AutowiredFieldElement#inject 这个方法就是为bean注入属性的地方,利用反射的方式。 beanFactory.resolveDependency(desc, beanName, autowiredBeanNames, typeConverter)获取到依赖的bean实例。所以接下来看如果获取依赖的Bean。 @Override protected void inject(Object bean, String beanName...

getField(),fieldError.getDefaultMessage()); } return JSON.toJSONString(error); } } 可以发现 ipAddress的错误信息里直接把内容输出出来,尝试 EL表达式注入。 跟一下大概的逻辑, 验证失败后,写入自定义的错误信息, 然后在抛出带有错误信息的MethodArgumentNotValidException异常。 后面就是Springboot捕获异常,...
