34 | 35 | public String mContextValue = "context value"; 36 | public static String sStaticValue = "static value"; 37 | 38 | public TestReflection(String a) { 39 | Log.d(TAG, "Constructor called :" + a); 40 | } 41 | 42 | public TestReflection(String a, String b) { 43 | Log.d(TAG, "Constructor called : a = " + a + ", b = " + b); 44 | } 45 | 46 | public String testContextInvoke(String a, int b) { 47 | Log.d(TAG, "Context invoke: a = " + a + ", b = " + b); 48 | return a + b; 49 | } 50 | 51 | public static String testStaticInvoke(String a, int b) { 52 | Log.d(TAG, "Static invoke: a = " + a + ", b = " + b); 53 | return a + b; 54 | } 55 | 56 | public static String testParamClassName(String a, int b) { 57 | Log.d(TAG, "testParamClassName: a = " + a + ", b = " + b); 58 | return a + b; 59 | } 60 | } 61 | 62 | ``` 63 | 可以写成如下接口 64 | ```java 65 | @BClass(top.niunaijun.app.bean.TestReflection.class) 66 | public interface TestReflection { 67 | 68 | @BConstructor 69 | top.niunaijun.app.bean.TestReflection _new(String a, String b); 70 | 71 | @BConstructor 72 | top.niunaijun.app.bean.TestReflection _new(String a); 73 | 74 | @BMethod 75 | String testContextInvoke(String a, int b); 76 | 77 | @BStaticMethod 78 | String testStaticInvoke(String a, int b); 79 | 80 | @BStaticMethod 81 | String testParamClassName(@BParamClassName("java.lang.String") Object a, int b); 82 | 83 | @BField 84 | String mContextValue(); 85 | 86 | @BStaticField 87 | String sStaticValue(); 88 | } 89 | 90 | ``` 91 | #### 2. build一次，让我生成相关的代码。 92 | 93 | #### 3. 可以尽情的反射代码 94 | 构造函数： 95 | ```java 96 | TestReflection testReflection = BRTestReflection.get()._new("a"); 97 | TestReflection testReflection = BRTestReflection.get()._new("a", "b"); 98 | ``` 99 | 100 | 反射方法： 101 | ```java 102 | // 静态方法 103 | BRTestReflection.get().testStaticInvoke("static", 0); 104 | 105 | // 上下文方法 106 | BRTestReflection.get(testReflection).testContextInvoke("context", 0); 107 | ``` 108 | 109 | 反射变量： 110 | ```java 111 | // 静态变量 112 | String staticValue = BRTestReflection.get().sStaticValue(); 113 | 114 | // 上下文变量 115 | String contextValue = BRTestReflection.get(testReflection).mContextValue(); 116 | ``` 117 | 118 | 设置变量： 119 | ```java 120 | // 静态变量 121 | BRTestReflection.get()._set_sStaticValue(staticValue + " changed"); 122 | 123 | // 上下文变量 124 | BRTestReflection.get(testReflection)._set_mContextValue(contextValue + " changed"); 125 | ``` 126 | BRTestReflection是程序自动生成的类，生成规则是BR + ClassName 127 | - BRTestReflection.get() 用于调用静态方法 128 | - BRTestReflection.get(caller) 用于调用非静态方法 129 | 130 | #### 注解说明 131 | 132 | 注解 | 注解方式 | 解释 133 | ---|---|--- 134 | @BClass | Type(Class) | 指定需要反射的类 135 | @BClassName | Type(Class) | 指定需要反射的类 136 | @BConstructor | Method | 注明是构造方法 137 | @BStaticMethod | Method | 注明是静态方法 138 | @BMethod | Method | 注明是非静态方法 139 | @BStaticField | Method | 注明是静态变量 140 | @BField | Method | 注明是非静态变量 141 | @BParamClass | Parameter | 注明该参数的Class，用于反射时寻找方法 142 | @BParamClassName | Parameter | 注明该参数的Class，用于反射时寻找方法 143 | 144 | ### 混淆配置 145 | ``` 146 | -keep class top.niunaijun.blackreflection.** {*;

Developer can use annotation to assign class, field and method. Then it will generate the reflection code automatically, developer don't need to write extra code to achieve Java Reflection. 6 | 7 | ## Usage 8 | 9 | ### Preparation 10 | 11 | #### Step 1. Configure your build.gradle (in top level directory) 12 | ```gradle 13 | allprojects { 14 | repositories { 15 | ... 16 | // Add 17 | maven { url 'https://jitpack.io' } 18 | } 19 | } 20 | ``` 21 | #### Step 2. Add BlackReflection dependencies 22 | ```gradle 23 | implementation 'com.github.CodingGay.BlackReflection:core:1.0.9' 24 | annotationProcessor 'com.github.CodingGay.BlackReflection:compiler:1.0.9' 25 | ``` 26 | 27 | ### Demo 28 | #### 1. If you need to reflect the methods of top.niunaijun.app.bean.TestReflection, please refer to：[MainActivity.java](https://github.com/CodingGay/BlackReflection/blob/main/app/src/main/java/top/niunaijun/app/MainActivity.java) 29 | ```java 30 | public class TestReflection { 31 | public static final String TAG = "TestConstructor"; 32 | 33 | public String mContextValue = "context value"; 34 | public static String sStaticValue = "static value"; 35 | 36 | public TestReflection(String a) { 37 | Log.d(TAG, "Constructor called :" + a); 38 | } 39 | 40 | public TestReflection(String a, String b) { 41 | Log.d(TAG, "Constructor called : a = " + a + ", b = " + b); 42 | } 43 | 44 | public String testContextInvoke(String a, int b) { 45 | Log.d(TAG, "Context invoke: a = " + a + ", b = " + b); 46 | return a + b; 47 | } 48 | 49 | public static String testStaticInvoke(String a, int b) { 50 | Log.d(TAG, "Static invoke: a = " + a + ", b = " + b); 51 | return a + b; 52 | } 53 | 54 | public static String testParamClassName(String a, int b) { 55 | Log.d(TAG, "testParamClassName: a = " + a + ", b = " + b); 56 | return a + b; 57 | } 58 | } 59 | 60 | ``` 61 | You can write an interface like this: 62 | ```java 63 | @BClass(top.niunaijun.app.bean.TestReflection.class) 64 | public interface TestReflection { 65 | 66 | @BConstructor 67 | top.niunaijun.app.bean.TestReflection _new(String a, String b); 68 | 69 | @BConstructor 70 | top.niunaijun.app.bean.TestReflection _new(String a); 71 | 72 | @BMethod 73 | String testContextInvoke(String a, int b); 74 | 75 | @BStaticMethod 76 | String testStaticInvoke(String a, int b); 77 | 78 | @BStaticMethod 79 | String testParamClassName(@BParamClassName("java.lang.String") Object a, int b); 80 | 81 | @BField 82 | String mContextValue(); 83 | 84 | @BStaticField 85 | String sStaticValue(); 86 | } 87 | 88 | ``` 89 | #### 2. Build your project, it will generate the code automatically. 90 | 91 | #### 3. Write the code heartily! 92 | Constructor: 93 | ```java 94 | TestReflection testReflection = BRTestReflection.get()._new("a"); 95 | TestReflection testReflection = BRTestReflection.get()._new("a", "b"); 96 | ``` 97 | 98 | Reflect Methods: 99 | ```java 100 | // Static Method 101 | BRTestReflection.get().testStaticInvoke("static", 0); 102 | 103 | // Non-static Method 104 | BRTestReflection.get(testReflection).testContextInvoke("context", 0); 105 | ``` 106 | 107 | Reflect Fields: 108 | ```java 109 | // Static Field 110 | String staticValue = BRTestReflection.get().sStaticValue(); 111 | 112 | // Non-static Field 113 | String contextValue = BRTestReflection.get(testReflection).mContextValue(); 114 | ``` 115 | 116 | Set the value of Fields: 117 | ```java 118 | // Static Field 119 | BRTestReflection.get()._set_sStaticValue(staticValue + " changed"); 120 | 121 | // Non-static Field 122 | BRTestReflection.get(testReflection)._set_mContextValue(contextValue + " changed"); 123 | ``` 124 | BRTestReflection is a class which generated by the program automatically. 125 | Generation rule: BR + ClassName 126 | - BRTestReflection.get() ------> It is used to invoke static method 127 | - BRTestReflection.get(caller) ------> It is used to invoke non-static method 128 | #### Annotation API 129 | 130 | Annotation | Target | Description 131 | ---|---|--- 132 | @BClass | Type(Class) | Assign the class which you want to manipulate 133 | @BClassName | Type(Class) | Assign the class which you want to manipulate 134 | @BConstructor | Method | Assign the constructor 135 | @BStaticMethod | Method | Assign the static method 136 | @BMethod | Method | Assign the non-static method 137 | @BStaticField | Method | Assign the static field 138 | @BField | Method | Assign the non-static field 139 | @BParamClass | Parameter | Assign the class of parameter 140 | @BParamClassName | Parameter | Assign the class of parameter 141 | 142 | ### Obfuscation rules 143 | ``` 144 | -keep class top.niunaijun.blackreflection.** {*;
