ClassFormatError: Thuộc tính mã không có trong phương thức không phải là bản địa hoặc trừu tượng trong tệp lớp javax/mail/MessagingException

Question

Tôi nhận được một số lạ ClassFormatError khi sử dụng api javaMail để gửi email trên ứng dụng web mvc mùa xuân của tôi.

Dưới đây là tôi thư cfg.xml

Answer 1

Bạn thường nhận được lỗi này khi bạn có nhiều mâu thuẫn JAR trong đường dẫn lớp học của bạn. Một trong những lý do phổ biến hơn là nếu bạn bao gồm một tạo phẩm trong classpath của bạn được cho là được cung cấp bởi vùng chứa ứng dụng. Nhìn vào POM của bạn, bạn có một số phụ thuộc thừa và chồng chéo. Di chuyển những bảng:

<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>servlet-api</artifactId> 
    <version>2.5</version> 
    <scope>provided</scope> 
</dependency> 
<dependency> 
    <groupId>javax.validation</groupId> 
    <artifactId>validation-api</artifactId> 
    <version>1.0.0.GA</version> 
</dependency> 
<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>jstl</artifactId> 
    <version>1.2</version> 
</dependency> 
<dependency> 
    <groupId>javax.mail</groupId> 
    <artifactId>mail</artifactId> 
    <version>1.4.3</version> 
</dependency> 
<dependency> 
    <groupId>javaee</groupId> 
    <artifactId>javaee-api</artifactId> 
    <version>5</version> 
</dependency> 

Và thay đổi phạm vi của sự phụ thuộc Java EE của bạn để 'cung cấp':

<dependency> 
    <groupId>javax</groupId> 
    <artifactId>javaee-api</artifactId> 
    <version>6.0</version> 
    <scope>provided</scope> 
</dependency> 

Cuối cùng, hãy chắc chắn bạn đang triển khai đến một máy chủ web Java EE 6 có khả năng, và lỗi nên biến mất.

--- Chỉnh sửa ---

Chỉ cần nhận thấy rằng bạn đang biên soạn với một mức độ tuân thủ Java 5. Thay đổi điều này:

<configuration> 
    <source>1.5</source> 
    <target>1.5</target> 
</configuration> 

Và tạo nguồn và giá trị mục tiêu 1.6.

Answer 2

javax:javaee-api được thiết kế để biên dịch, không chạy, bao gồm kiểm tra đơn vị. Nếu bạn cần các lớp phù hợp để chạy, hãy chạy với máy chủ ứng dụng Java EE.

Ngoài ra, tên chính xác là Java EE, không phải JEE.

Answer 3

Tôi đã gặp một vấn đề tương tự, ... do đó, khi tôi đang chạy JUnit một lỗi xảy ra:

Absent Code attribute in method that is not native or abstract in class file javax/servlet/http/HttpServlet 

tôi giải quyết nó thêm phụ thuộc sau đây (lần đầu tiên một):

<dependency> 
    <groupId>org.glassfish.main.extras</groupId> 
    <artifactId>glassfish-embedded-all</artifactId> 
    <version>3.1.2.2</version> 
    <scope>test</scope> 
</dependency> 

Answer 4

Tôi cũng phải đối mặt với cùng loại ngoại lệ khi chạy junits với jmock và maven:

Exception in constructor: testDoExecute (java.lang.ClassFormatError: Absent Code attribute in method that is not native or abstract in class file javax/servlet/http/Cookie at java.lang.ClassLoader.defineClass1(Native Method)

Đó là do các lớp mã của bạn cố gắng truy cập không có sẵn trong javaee api jar được sử dụng trong dự án vì mã của bạn biên dịch đối với các lớp không đầy đủ, như JavaEE6 Api và các bài kiểm tra Đơn vị của bạn cố gắng truy cập mã không có. JUnit sẽ chỉ đơn giản là thất bại và đánh dấu kiểm tra là lỗi, in một cái gì đó giống như ngoại lệ trên.

Nó có thể được giải quyết bằng cách thêm javax.servlet jar/phụ thuộc hoặc phiên bản jar thay đổi JavaEE hiển thị dưới đây:

<dependency> 
    <groupId>javax.servlet</groupId> 
    <artifactId>servlet-api</artifactId> 
    <version>2.5</version> 
</dependency> 

**OR** 

<dependency> 
    <groupId>javax.j2ee</groupId> 
    <artifactId>j2ee</artifactId> 
    <version>1.4</version> 
    <scope>provided</scope> 
</dependency> 

PS: Vui lòng thêm phiên bản jar tương thích với bạn lọ khác hiện có trong dự án.
