操作步骤

1、在包含Controller类的module下（以下简称A）添加jar包

jar包可以在https://github.com/Lovnx/confusion这个示例中得到

2、在A的pom.xml中添加

<build>
        <finalName>${finalName}</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <mainClass>你的启动类</mainClass>
                    <includeSystemScope>true</includeSystemScope>
                    <fork>true</fork>
                </configuration>
                <executions>
                    <execution>
                        <goals>
                            <goal>repackage</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
            <!-- Allatori plugin start -->
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-resources-plugin</artifactId>
                <version>2.6</version>
                <executions>
                    <execution>
                        <id>copy-and-filter-allatori-config</id>
                        <phase>package</phase>
                        <goals>
                            <goal>copy-resources</goal>
                        </goals>
                        <configuration>
                            <outputDirectory>${basedir}/target</outputDirectory>
                            <resources>
                                <resource>
                                    <directory>${basedir}/allatori</directory>
                                    <includes>
                                        <include>allatori.xml</include>
                                    </includes>
                                    <filtering>true</filtering>
                                </resource>
                            </resources>
                        </configuration>
                    </execution>
                </executions>
            </plugin>
            <plugin>
                <groupId>org.codehaus.mojo</groupId>
                <artifactId>exec-maven-plugin</artifactId>
                <version>1.2.1</version>
                <executions>
                    <execution>
                        <id>run-allatori</id>
                        <phase>package</phase>
                        <goals>
                            <goal>exec</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    <executable>java</executable>
                    <arguments>
                        <argument>-Xms128m</argument>
                        <argument>-Xmx512m</argument>
                        <argument>-jar</argument>
                        <argument>${basedir}/lib/allatori.jar</argument>
                        <argument>${basedir}/target/allatori.xml</argument>
                    </arguments>
                </configuration>
            </plugin>
            <!-- Allatori plugin end -->
        </plugins>
    </build>

3、在A的resources目录下添加文件allatori.xml，内容如下

<config>
    <input>
        <!-- in中是待混淆的jar包，out是混淆后的jar包，路径是相对本配置文件所在位置 -->
        <!-- 这个示例中，A.jar是工程jar包，B.jar是子模块jar包 -->
        <jar in="A.jar" out="A-obfuscated.jar"/>
        <jar in="../../B/target/B.jar" out="B.jar"/> 
    </input>

    <!-- ignore-classes中配置不被混淆的类 -->
    <ignore-classes>
        <!-- 配置了启动相关类不被混淆，保证springboot可以正常启动 -->
        <class template="class 启动类"/>

        <class template="class *springframework*"/>
        <class template="class *alibaba*"/>
        <class template="class *persistence*"/>
        <class template="class *apache*"/>

        <class template="class *model*"/>
        <class template="class *enums*"/>
        <class template="class *repository*"/>
    </ignore-classes>

    <keep-names>
        <!-- 防止部分类、方法、变量找不到名称而报错 -->
        <!-- 所有方法名称不变，parameters="keep"表示方法参数名也不变 -->
        <method template="*(**)" parameters="keep"/>
        <!-- com.a.b.c中的类以及其子包中的类的名称不变 -->
        <class template="class com.a.b.c.*"/>
    </keep-names>

    <!-- 混淆前后的映射关系保存在log.xml中 -->
    <property name="log-file" value="log.xml"/>
</config>
