在Spring Boot项目中集成Jasypt（Java Simplified Encryption）

```xml
    com.github.ulisesbocchio
    jasypt-spring-boot-starter
    3.0.4
```

```properties

jasypt.encryptor.algorithm=PBEWithMD5AndDES

jasypt.encryptor.password=mySecretKey
```

```java
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Component;
 
@Component
public class MyComponent {
 
    // 加密的值
    @Value("${encrypted.property}")
    private String encryptedProperty;
 
    // 注入的解密后的值
    @Value("${decrypted.property}")
    private String decryptedProperty;
 
    // Getter 和 Setter 方法
    public String getEncryptedProperty() {
        return encryptedProperty;
    }
 
    public void setEncryptedProperty(String encryptedProperty) {
        this.encryptedProperty = encryptedProperty;
    }
 
    public String getDecryptedProperty() {
        return decryptedProperty;
    }
 
    public void setDecryptedProperty(String decryptedProperty) {
        this.decryptedProperty = decryptedProperty;
    }
}
```

```properties
# 加密后的值
encrypted.property=ENC(encryptedValue)
 
# 解密后的值
decrypted.property=DEC(encryptedValue)
```
 
#### 使用工具类加密和解密
 
```java
import org.jasypt.encryption.StringEncryptor;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
 
@Component
public class MyEncryptor {
 
    private final StringEncryptor encryptor;
 
    @Autowired
    public MyEncryptor(StringEncryptor encryptor) {
        this.encryptor = encryptor;
    }
 
    // 加密方法
    public String encrypt(String input) {
        return encryptor.encrypt(input);
    }
 
    // 解密方法
    public String decrypt(String encryptedMessage) {
        return encryptor.decrypt(encryptedMessage);
    }
}
```

```properties
my.secret.property=ENC(encryptedValue)
```

```java
@TestPropertySource(properties = {
    "jasypt.encryptor.password=myTestKey",
    "encrypted.property=ENC(encryptedValue)"
})
public class MyIntegrationTest {
    // 测试代码
}
```
