web3Jplugin

根据solidity合约生成java包装类
maven插件（https://github.com/web3j/web3j-maven-plugin
）
1:引入依赖 web3j

            <dependency>
                <groupId>org.web3j</groupId>
                <artifactId>core</artifactId>
                <version>4.5.11</version>
            </dependency>

2.引入插件

<plugin>
    <groupId>org.web3j</groupId>
    <artifactId>web3j-maven-plugin</artifactId>
    <version>4.5.11</version>
    <configuration>
        <packageName>com.zuehlke.blockchain.model</packageName>
        <sourceDestination>src/main/java/generated</sourceDestination>
        <nativeJavaType>true</nativeJavaType>
        <outputFormat>java,bin</outputFormat>
        <soliditySourceFiles>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.sol</include>
            </includes>
        </soliditySourceFiles>
        <outputDirectory>
            <java>src/java/generated</java>
            <bin>src/bin/generated</bin>
            <abi>src/abi/generated</abi>
        </outputDirectory>
        <contract>
            <includes>
                <include>greeter</include>
            </includes>
            <excludes>
                <exclude>mortal</exclude>
            </excludes>
        </contract>
        <pathPrefixes>
            <pathPrefix>dep=../dependencies</pathPrefix>
        </pathPrefixes>
    </configuration>
</plugin>

3.修改好文件目录后 在项目目录执行命令 mvn web3j:generate-sources
