Question

我是Spring和AOP的新手。我正在尝试这个简单的事情，我创建了一个自定义注释，在任何方法之前放置应该执行一些代码。这是我创建的注释

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "pacra1";


$conn = new mysqli($servername, $username, $password, $dbname);

"SET @v1 := (SELECT `opinion_id` FROM `pacra_client_opinion_relations` WHERE `client_id` = 97 LIMIT 1)";
$sql= " SELECT @v1, r.client_id,c.id,t.id,a.id,o.id,c.name as opinion, r.notification_date, t.title as ttitle,a.title as atitle,o.title as otitle, l.title as ltitle, s.title as stitle, pr.opinion_id, pc.id, pr.client_id as pr_client, pc.address, pc.liaison_one, city.id, pc.head_office_id, city.city, pc.title as cname
FROM og_ratings r 
LEFT JOIN og_companies c
ON r.client_id = c.id
LEFT JOIN og_rating_types t
ON r.rating_type_id = t.id
LEFT JOIN og_actions a
ON r.pacra_action = a.id
LEFT JOIN og_outlooks o
ON r.pacra_outlook = o.id
LEFT JOIN og_lterms l
ON r.pacra_lterm = l.id
LEFT JOIN og_sterms s
ON r.pacra_sterm = s.id
LEFT JOIN   companies_contact co
ON c.id = co.companies_id
LEFT JOIN pacra_client_opinion_relations pr
ON pr.opinion_id = c.id
LEFT JOIN pacra_clients pc
ON pc.id = pr.client_id
LEFT JOIN city
ON city.id = pc.head_office_id
WHERE r.client_id= @v1
ORDER BY r.id DESC
LIMIT 1";

$result = $conn->query($sql);
while ($row = $result->fetch_assoc()){

    $liaison_one = $row['liaison_one'];
    echo $liaison_one;

}




?>

接下来，我创建了包含逻辑

的Spring Aspect类

    // Declares a custom annotation that validates json
    @Retention(RetentionPolicy.RUNTIME)
    @Target(ElementType.METHOD)
    public @interface JsonSchemaAnnotation {
    }

这是我的简单测试类

@Aspect
public class UpdateUIMetadataInterceptor {

@Pointcut("execution(public * com.fico.cardinal.cm.*.*(..))")
public void anyPublicMethod() {
    System.out.println("Running");
}

@Before("anyPublicMethod() && @annotation(jsonSchemaAnnotation)")
public void validateJson(ProceedingJoinPoint pjp) throws Throwable {
    System.out.println("Running");  
}

}

问题是我的春天永远不会被触发。我在public class ValidationTest { public static void main(String[] args) { ApplicationContext context = new ClassPathXmlApplicationContext("spring/configuration.xml"); String jsondata = "{\"id\": \"EXPENSE_REPORT\",\"properties\": {\"transactionType\": \"EXPENSE_REPORT\"},\"sections\": []} ]}"; ValidationTest test = new ValidationTest(); test.jsonValidationTest("dummy", jsondata); ((AbstractApplicationContext) context).close(); } @JsonSchemaAnnotation public void jsonValidationTest(String dummy, String jsondata) { System.out.println("Success"); }

中添加了一个bean

configuration.xml

有人能说出我错过的东西吗？

Answer 1

您的代码有几个问题：

您应该将您的${token}对象创建为由Spring管理的bean而不是使用新的
ValidationTest应为<aop:include name="UpdateUIMetadataInterceptor" />;为了简单起见，你实际上可以坚持使用<aop:include name="updateUI"/>
<aop:aspectj-autoproxy/>，因此将其删除;如果您需要访问参数

ProceedingJoinPoint

JoinPoint

JsonSchemaAnnotation jsonSchemaAnnotation

Answer 2

我认为您需要完全限定名称或方法中的参数：

FQN：

@Before("anyPublicMethod() && @annotation(your.package.JsonSchemaAnnotation)")
public void validateJson(ProceedingJoinPoint pjp) throws Throwable {
    System.out.println("Running");  
}

参数：

@Before("anyPublicMethod() && @annotation(jsonSchemaAnnotation)")
public void validateJson(ProceedingJoinPoint pjp, JsonSchemaAnnotation jsonSchemaAnnotation ) throws Throwable {
    System.out.println("Running");  
}

（你也需要使用豆子，正如Dmitry Kuskov指出的那样

Spring AOP Pointcut不会触发
