它會返回錯誤：

Byte data not found at : data:image/svg+xml;base64, ... 

而在PDF渲染，但只適用於HTML出口。 正如一些職位的建議，我嘗試使用

net.sf.jasperreports.renderers.BatikRenderer.getInstance(new java.net.URL("data:...")) 

，但它也不能工作。

有人可能會建議一種方法，將在所有類型的出口顯示嵌入式圖像？

Answer 1

我還沒有用svg試過它，但我得到它與一個PNG圖像工作。 你必須添加導入org.apache.commons.codec.binary.Base64，你應該刪除從base64編碼數據的標題：data:image/svg+xml;base64,

現在可以解碼，並用該表達式傳遞數據：new ByteArrayInputStream(new Base64().decodeBase64($P{logo}.getBytes("UTF-8")))。

在你的情況應該是這樣的：在碧玉PDF報告中嵌入SVG的

Answer 2

我終於解決了問題。

使用原始SVG圖像數據而不使用data:image/svg+xml;base64。使用net.sf.jasperreports.renderers.BatikRenderer來渲染SVG圖像。 Maven的依賴，包括這個類是以下內容：

<dependency> 
    <groupId>org.apache.xmlgraphics</groupId> 
    <artifactId>batik-bridge</artifactId> 
    <version>1.7</version> 
</dependency> 

使用完全合格的類名org.apache.commons.codec.binary.Base64代替Base64。 Maven的依賴，包括這個類是以下內容：

<dependency> 
    <groupId>commons-codec</groupId> 
    <artifactId>commons-codec</artifactId> 
    <version>1.10</version> 
</dependency>
